The requirement to perform complicated statistic analysis of big data by institutions of engineering, scientific research, health care, commerce, banking and computer research is immense. However, the limitations of the widely used current desktop software like R, excel, minitab and spss gives a researcher limitation to deal with big data and big data analytic tools like IBM BigInsight, HP Vertica, SAP HANA & Pentaho come at an overpriced license. Apache Hadoop is an open source distributed computing framework that uses commodity hardware. With this project, I intend to collaborate Apache Hadoop and R software to develop an analytic platform that stores big data (using open source Apache Hadoop) and perform statistical analysis (using open source R software).Due to the limitations of vertical scaling of computer unit, data storage is handled by several machines and so analysis becomes distributed over all these machines. Apache Hadoop is what comes handy in this environment. To store massive quantities of data as required by researchers, we could use commodity hardware and perform analysis in distributed environment.

Advanced data science techniques, like machine learning, have proven an extremely useful tool to derive valuable insights from existing data. Platforms like Spark, and complex libraries for R, Python and Scala put advanced techniques at the fingertips of the data scientists. However, these data scientists spend most of their time looking for the right data and massaging it into a usable format. Data virtualization offers a new alternative to address these issues in a more efficient and agile way.
Watch this on-demand session to learn how companies can use data virtualization to:
- Create a logical architecture to make all enterprise data available for advanced analytics exercise
- Accelerate data acquisition and massaging, providing the data scientist with a powerful tool to complement their practice
- Integrate popular tools from the data science ecosystem: Spark, Python, Zeppelin, Jupyter, etc.
We are in the age of big data which involves collection of large datasets.Managing and processing large data sets is difficult with existing traditional database systems.Hadoop and Map Reduce has become one of the most powerful and popular tools for big data processing . Hadoop Map Reduce a powerful programming model is used for analyzing large set of data with parallelization, fault tolerance and load balancing and other features are it is elastic,scalable,efficient.MapReduce with cloud is combined to form a framework for storage, processing and analysis of massive machine maintenance data in a cloud computing environment.
Big data is data that, by virtue of its velocity, volume, or variety (the three Vs), cannot be easily stored or analyzed with traditional methods. Hadoop is an open-source software framework for storing data and running applications on clusters of commodity hardware.
Big data is the term for any gathering of information sets, so expensive and complex, that it gets to be hard to process for utilizing customary information handling applications. The difficulties incorporate investigation, catch, duration, inquiry, sharing, stockpiling, Exchange, perception, and protection infringement. To reduce spot business patterns, anticipate diseases, conflict etc., we require bigger data sets when compared with the smaller data sets. Enormous information is hard to work with utilizing most social database administration frameworks and desktop measurements and perception bundles, needing rather enormously parallel programming running on tens, hundreds, or even a large number of servers. In this paper there was an observation on Hadoop architecture, different tools used for big data and its security issues.

Big Data Analysis Patterns - TriHUG 6/27/2013boorad
Big Data Analysis Patterns: Tying real world use cases to strategies for analysis using big data technologies and tools.
Big data is ushering in a new era for analytics with large scale data and relatively simple algorithms driving results rather than relying on complex models that use sample data. When you are ready to extract benefits from your data, how do you decide what approach, what algorithm, what tool to use? The answer is simpler than you think.
This session tackles big data analysis with a practical description of strategies for several classes of application types, identified concretely with use cases. Topics include new approaches to search and recommendation using scalable technologies such as Hadoop, Mahout, Storm, Solr, & Titan.
These slides use concepts from my (Jeff Funk) course entitled analyzing hi-tech opportunities to analyze how Big Data is becoming economically feasible for health care. These slides describe how the cost of sensors, data processing, data storage and data analyzing are falling, how new and better forms of storage and algorithms are being implemented, and what this means for sustainable health care. These changes are enabling a move towards personalized health care.
It is almost impossible to escape the topic of Data Science. While the core of Data Science has remained the same over the last decade, it’s emergence to the forefront is spurred by both the availability of new data types and a true realization of the value that it delivers. In this session, we will provide an overview of data science, the different classes of machine learning algorithm and deliver an end-to-end demonstration of performing Machine Learning Using Hadoop. Audience: Developers, Data Scientist Architects and System Engineers.

In today’s context, the big data market is rapidly undergoing contortions that define market maturity, such as consolidation. Big data refers to large volumes of data. This can be both structured and unstructured data. Big data is data that is huge in size and grows exponentially with time. As the data is too large and complex, traditional data management tools are not sufficient for storing or processing it efficiently. But analyzing big data is crucial to know the patterns and trends to be adopted to improve your business.
Big data is used for structured, unstructured and semi-structured large volume of data which is difficult to
manage and costly to store. Using explanatory analysis techniques to understand such raw data, carefully
balance the benefits in terms of storage and retrieval techniques is an essential part of the Big Data. The
research discusses the Map Reduce issues, framework for Map Reduce programming model and
implementation. The paper includes the analysis of Big Data using Map Reduce techniques and identifying
a required document from a stream of documents. Identifying a required document is part of the security in
a stream of documents in the cyber world. The document may be significant in business, medical, social, or
terrorism.
Fully featured, commercially supported machine learning suites that can build Decision Trees in Hadoop are few and far between. Addressing this gap, Revolution Analytics recently enhanced its entire scalable analytics suite to run in Hadoop. In this talk, I will explain how our Decision Tree implementation exploits recent research reducing the computational complexity of decision tree estimation, allowing linear scalability with data size and number of nodes. This streaming algorithm processes data in chunks, allowing scaling unconstrained by aggregate cluster memory. The implementation supports both classification and regression and is fully integrated with the R statistical language and the rest of our advanced analytics and machine learning algorithms, as well as our interactive Decision Tree visualizer.
Big data analytics is the use of advanced analytic techniques against very large, diverse data sets that include different types such as structured/unstructured and streaming/batch, and different sizes from terabytes to zettabytes. Big data is a term applied to data sets whose size or type is beyond the ability of traditional relational databases to capture, manage, and process the data with low-latency. And it has one or more of the following characteristics – high volume, high velocity, or high variety. Big data comes from sensors, devices, video/audio, networks, log files, transactional applications, web, and social media - much of it generated in real time and in a very large scale.
Analyzing big data allows analysts, researchers, and business users to make better and faster decisions using data that was previously inaccessible or unusable. Using advanced analytics techniques such as text analytics, machine learning, predictive analytics, data mining, statistics, and natural language processing, businesses can analyze previously untapped data sources independent or together with their existing enterprise data to gain new insights resulting in significantly better and faster decisions.
Big data analytics is the process of examining large data sets containing a variety of data types i.e., big data to uncover hidden patterns, unknown correlations, market trends, customer preferences and other useful business information. The analytical findings can lead to more effective marketing, new revenue opportunities, better customer service, improved operational efficiency, competitive advantages over rival organizations and other business benefits. Enterprises are increasingly looking to find actionable insights into their data. Many big data projects originate from the need to answer specific business questions. With the right big data analytics platforms in place, an enterprise can boost sales, increase efficiency, and improve operations, customer service and risk management. Notably, the business area getting the most attention relates to increasing efficiencies and optimizing operations. By using big data analytics you can extract only the relevant information from terabytes, petabytes and exabytes, and analyse it to transform your business decisions for the future. Becoming proactive with big data analytics isn't a one-time endeavour, it is more of a culture change – a new way of gaining ground.

Bigdata.
Big data is a term for data sets that are so large or complex that traditional data processing application software is inadequate to deal with them. Challenges include capture, storage, analysis, data curation, search, sharing, transfer, visualization, querying, updating and information privacy. The term "big data" often refers simply to the use of predictive analytics, user behavior analytics, or certain other advanced data analytics methods that extract value from data, and seldom to a particular size of data set. "There is little doubt that the quantities of data now available are indeed large, but that’s not the most relevant characteristic of this new data ecosystem."[2] Analysis of data sets can find new correlations to "spot business trends, prevent diseases, combat crime and so on."[3] Scientists, business executives, practitioners of medicine, advertising and governments alike regularly meet difficulties with large data-sets in areas including Internet search, fintech, urban informatics, and business informatics. Scientists encounter limitations in e-Science work, including meteorology, genomics,[4] connectomics, complex physics simulations, biology and environmental research.[5]
Data sets grow rapidly - in part because they are increasingly gathered by cheap and numerous information-sensing Internet of things devices such as mobile devices, aerial (remote sensing), software logs, cameras, microphones, radio-frequency identification (RFID) readers and wireless sensor networks.[6][7] The world's technological per-capita capacity to store information has roughly doubled every 40 months since the 1980s;[8] as of 2012, every day 2.5 exabytes (2.5×1018) of data are generated.[9] One question for large enterprises is determining who should own big-data initiatives that affect the entire organization.[10]
Relational database management systems and desktop statistics- and visualization-packages often have difficulty handling big data. The work may require "massively parallel software running on tens, hundreds, or even thousands of servers".[11] What counts as "big data" varies depending on the capabilities of the users and their tools, and expanding capabilities make big data a moving target. "For some organizations, facing hundreds of gigabytes of data for the first time may trigger a need to reconsider data management options. For others, it may take tens or hundreds of terabytes before data size becomes a significant consideration."

From Vaccine Management to ICU Planning: How CRISP Unlocked the Power of Data...Databricks
Chesapeake Regional Information System for our Patients (CRISP) is a nonprofit healthcare information exchange (HIE) whose customers include states like Maryland and healthcare providers such as Johns Hopkins. CRISP’s work supports the local healthcare community by securely sharing the kind of data that facilitates care and improves health outcomes.
When the pandemic started, the Maryland Department of Health reached out to CRISP with a request: Get us the demographic data we need to track COVID-19 and proactively support our communities. As a result, CRISP employees spent long hours attempting to handle multiple data sources with complex data enrichment processes. To automate these requests, CRISP partnered with Slalom to build a data platform powered by Databricks and Delta Lake.
Using the power of the Databricks Lakehouse platform and the flexibility of Delta Lake, Slalom helped CRISP provide the Maryland Department of Health with near real-time reporting of key COVID-19 measures. With this information, Maryland has been able to track the path of the pandemic, target the locations of new testing sites, and ultimately improve access for vulnerable communities.
The work did not stop there—once CRISP’s customers saw the value of the platform, more requests starting coming in. Now, nearly one year since the platform was created, CRISP has processed billons of records from hundreds of data sources in an effort to combat the pandemic. Notable outcomes from the work include hourly contact tracing with data already cross-referenced for individual risk factors, automated reporting on COVID-19 hospitalizations, real-time ICU capacity reporting for EMTs, tracking of COVID-19 patterns in student populations, tracking of the vaccination campaign, connecting Maryland MCOs to vulnerable people who need to be prioritized for the vaccine, and analysis of the impact of COVID-19 on pregnancies.

Mankind has stored more than 295 billion gigabytes (or 295 Exabyte) of data since 1986, as per a report by the University of Southern California. Storing and monitoring this data in widely distributed environments for 24/7 is a huge task for global service organizations. These datasets require high processing power which can’t be offered by traditional databases as they are stored in an unstructured format. Although one can use Map Reduce paradigm to solve this problem using java based Hadoop, it cannot provide us with maximum functionality. Drawbacks can be overcome using Hadoop-streaming techniques that allow users to define non-java executable for processing this datasets. This paper proposes a THESAURUS model which allows a faster and easier version of business analysis.

The Impact of Digital Media on the Decentralization of Power and the Erosion ...ijtsrd
The impact of digital media on the distribution of power and the weakening of traditional gatekeepers has gained considerable attention in recent years. The adoption of digital technologies and the internet has resulted in declining influence and power for traditional gatekeepers such as publishing houses and news organizations. Simultaneously, digital media has facilitated the emergence of new voices and players in the media industry. Digital medias impact on power decentralization and gatekeeper erosion is visible in several ways. One significant aspect is the democratization of information, which enables anyone with an internet connection to publish and share content globally, leading to citizen journalism and bypassing traditional gatekeepers. Another aspect is the disruption of conventional media industry business models, as traditional organizations struggle to adjust to the decrease in advertising revenue and the rise of digital platforms. Alternative business models, such as subscription models and crowdfunding, have become more prevalent, leading to the emergence of new players. Overall, the impact of digital media on the distribution of power and the weakening of traditional gatekeepers has brought about significant changes in the media landscape and the way information is shared. Further research is required to fully comprehend the implications of these changes and their impact on society.

The Role of Mentoring and Its Influence on the Effectiveness of the Teaching ...ijtsrd
This paper reports on a study which was conducted to investigate the role of mentoring and its influence on the effectiveness of the teaching of Physics in secondary schools in the South West Region of Cameroon. The study adopted the convergent parallel mixed methods design, focusing on respondents in secondary schools in the South West Region of Cameroon. Both quantitative and qualitative data were collected, analysed separately, and the results were compared to see if the findings confirm or disconfirm each other. The quantitative analysis found that majority of the respondents 72 of Physics teachers affirmed that they had more experienced colleagues as mentors to help build their confidence, improve their teaching, and help them improve their effectiveness and efficiency in guiding learners’ achievements. Only 28 of the respondents disagreed with these statements. With majority respondents 72 agreeing with the statements, it implies that in most secondary schools, experienced Physics teachers act as mentors to build teachers’ confidence in teaching and improving students’ learning. The interview qualitative data analysis summarized how secondary school Principals use meetings with mentors and mentees to promote mentorship in the school milieu. This has helped strengthen teachers’ classroom practices in secondary schools in the South West Region of Cameroon. With the results confirming each other, the study recommends that mentoring should focus on helping teachers employ social interactions and instructional practices feedback and clarity in teaching that have direct measurable impact on students’ learning achievements.

This study primarily focuses on the design of a high side buck converter using an Arduino microcontroller. The converter is specifically intended for use in DC DC applications, particularly in standalone solar PV systems where the PV output voltage exceeds the load or battery voltage. To evaluate the performance of the converter, simulation experiments are conducted using Proteus Software. These simulations provide insights into the input and output voltages, currents, powers, and efficiency under different state of charge SoC conditions of a 12V,70Ah rechargeable lead acid battery. Additionally, the hardware design of the converter is implemented, and practical data is collected through operation, monitoring, and recording. By comparing the simulation results with the practical results, the efficiency and performance of the designed converter are assessed. The findings indicate that while the buck converter is suitable for practical use in standalone PV systems, its efficiency is compromised due to a lower output current.

Sustainable Energy by Paul A. Adekunte | Matthew N. O. Sadiku | Janet O. Sadikuijtsrd
Energy becomes sustainable if it meets the needs of the present without compromising the ability of future generations to meet their own needs. Some of the definitions of sustainable energy include the considerations of environmental aspects such as greenhouse gas emissions, social, and economic aspects such as energy poverty. Generally far more sustainable than fossil fuel are renewable energy sources such as wind, hydroelectric power, solar, and geothermal energy sources. Worthy of note is that some renewable energy projects, like the clearing of forests to produce biofuels, can cause severe environmental damage. The sustainability of nuclear power which is a low carbon source is highly debated because of concerns about radioactive waste, nuclear proliferation, and accidents. The switching from coal to natural gas has environmental benefits, including a lower climate impact, but could lead to delay in switching to more sustainable options. “Carbon capture and storage” can be built into power plants to remove the carbon dioxide CO2 emissions, but this technology is expensive and has rarely been implemented. Leading non renewable energy sources around the world is fossil fuels, coal, petroleum, and natural gas. Nuclear energy is usually considered another non renewable energy source, although nuclear energy itself is a renewable energy source, but the material used in nuclear power plants is not. The paper addresses the issue of sustainable energy, its attendant benefits to the future generation, and humanity in general. Paul A. Adekunte | Matthew N. O. Sadiku | Janet O.

Concepts for Sudan Survey Act Implementations Executive Regulations and Stand...ijtsrd
This paper aims to outline the executive regulations, survey standards, and specifications required for the implementation of the Sudan Survey Act, and for regulating and organizing all surveying work activities in Sudan. The act has been discussed for more than 5 years. The Land Survey Act was initiated by the Sudan Survey Authority and all official legislations were headed by the Sudan Ministry of Justice till it was issued in 2022. The paper presents conceptual guidelines to be used for the Survey Act implementation and to regulate the survey work practice, standardizing the field surveys, processing, quality control, procedures, and the processes related to survey work carried out by the stakeholders and relevant authorities in Sudan. The conceptual guidelines are meant to improve the quality and harmonization of geospatial data and to aid decision making processes as well as geospatial information systems. The established comprehensive executive regulations will govern and regulate the implementation of the Sudan Survey Geomatics Act in all surveying and mapping practices undertaken by the Sudan Survey Authority SSA and state local survey departments for public or private sector organizations. The targeted standards and specifications include the reference frame, projection, coordinate systems, and the guidelines and specifications that must be followed in the field of survey work, processes, and mapping products. In the last few decades, there has been a growing awareness of the importance of geomatics activities and measurements on the Earths surface in space and time, together with observing and mapping the changes. In such cases, data must be captured promptly, standardized, and obtained with more accuracy and specified in much detail. The paper will also highlight the current situation in Sudan, the degree to which survey standards are used, the problems encountered, and the errors that arise from not using the standards and survey specifications.

Towards the Implementation of the Sudan Interpolated Geoid Model Khartoum Sta...ijtsrd
The discussions between ellipsoid and geoid have invoked many researchers during the recent decades, especially during the GNSS technology era, which had witnessed a great deal of development but still geoid undulation requires more investigations. To figure out a solution for Sudans local geoid, this research has tried to intake the possibility of determining the geoid model by following two approaches, gravimetric and geometrical geoid model determination, by making use of GNSS leveling benchmarks at Khartoum state. The Benchmarks are well distributed in the study area, in which, the horizontal coordinates and the height above the ellipsoid have been observed by GNSS while orthometric heights were carried out using precise leveling. The Global Geopotential Model GGM represented in EGM2008 has been exploited to figure out the geoid undulation at the benchmarks in the study area. This is followed by a fitting process, that has been done to suit the geoid undulation data which has been computed using GNSS leveling data and geoid undulation inspired by the EGM2008. Two geoid surfaces were created after the fitting process to ensure that they are identical and both of them could be counted for getting the same geoid undulation with an acceptable accuracy. In this respect, statistical operation played an important role in ensuring the consistency and integrity of the model by applying cross validation techniques splitting the data into training and testing datasets for building the geoid model and testing its eligibility. The geometrical solution for geoid undulation computation has been utilized by applying straightforward equations that facilitate the calculation of the geoid undulation directly through applying statistical techniques for the GNSS leveling data of the study area to get the common equation parameters values that could be utilized to calculate geoid undulation of any position in the study area within the claimed accuracy. Both systems were checked and proved eligible to be used within the study area with acceptable accuracy which may contribute to solving the geoid undulation problem in the Khartoum area, and be further generalized to determine the geoid model over the entire country, and this could be considered in the future, for regional and continental geoid model.

The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

analysis is largely left neglected. The analysis
functionality is overlooked by researchers as they feel
that these Data Management Systems are competent
enough at data storage, data processing and simple

2. LITERATURE SURVEY
2.1 Open Source R Programming Language
The R[6][7][8][10] is a free software programming
language used among statisticians and data miners for
statistical computing, graphics and several such
applications. When Ross Ihaka and Robert Gentleman
created “R” in the year 1993, the appreciation and
world wide acceptance [14] it generated, prompted
them to make it available to the general public over
the internet under the GPL. With this move R became
open to a wider public and in no time, it took over
much of the statistical analysis over the machine and
development of the language with time made it the
most eligible and updated software programming
language in the industry. R was released on 29th
February 2000 can be used freely, distributed and sold
to any receiver who possess the same rights. The
flexibility of the language due to it’s being based on a
formal computer language, makes it the most sought
after software programming language in the market.
R is rich in various statistical analysis packages.
There are 5922 packages available in CRAN packages
repository [16]. This is again increasing
exponentially. There are many R users and many
forums as well as groups from where you can be get
concept mind as well as tutorial and support available.
2.2 Open Source Apache Hadoop
Apache Hadoop[3][4][5][7][11][12] readies us with
an easy to use, dependable and accurate distributed
computing software whose main purpose is to enable
the researcher to shift from single server to multiple
connected machines each functioning as a separate
unit as far as data storage and computing is
concerned. By utilizing the Apache Hadoop software
library that has several thousand computers over a
cluster, one can be cent percent assured of the
accuracy of analysis as each unit is so programmed as
to be able to spot and rectify errors.
Hadoop stores massive quantities of data over several
systems in the cluster and comes up with solutions
through a highly scalable, distributed batch processing
system. In this way, a large workload is distributed
over the cluster of several inexpensive datasets and
big data analysis is done over with in a very short
time. The Apache Hadoop framework is composed of
the following modules:
1. Hadoop Common: This is the basic module that is
concerned with libraries and ther such utilities that are
essential for the optimal functioning of other hadoop
modules.
2. Hadoop Distributed File System (HDFS™): This is
the module that concerns itself with data storage over
several storage systems wherein information is
submitted to commodity machines in a classified
fashion. It is under the functionality of this module
that the bandwidth of a cluster is kept at a high level.
3. Hadoop YARN: Where YARN stands for Yet
Another Resource Negotiator, is as the name suggests
a task assigning and resource managing module
performing at the cluster level. It is a generic platform
required for any distributed application to run on.
4. Hadoop MapReduce: A sub project of the Apache
Hadoop project, this project is a yarn based system
that is concerned with distributing input and output
data in chunks for parallel processing.
2.3 RHadoop
RHadoop[7][10][14][15][17] is an open source
project aimed at large scale data analysts to empower
them to use the horizontal scalability oh Hadoop using
the R language. ravro, plymr, rmr, rhdfs and rhbase,
the 5 R packages enable its users to manage and
analyze massive quantities of information using
Hadoop.
1. ravro – It is the R package which permits the
reading and writing of files in avro format, to R.
2. Plyrmr – It is a more recent R package that makes
R and Hadoop perform in near perfect if not perfect
harmony, in the analysis of higher lever plyr like data.
3. Rmr – It is an R package that came into being to
allow users to write map reduce programs in R since it
is more productive and far easier.
4. Rhdfs – It is an R package that gives
administration of HDFS files from within R. It uses
Hadoop common to give access to map reduce file
services.
5. Rhbase – It is an R package that allows its users
basic connectivity to Hbase. Administrating a
database for Hbase by using R is made possible by
rhbase.

3. SYSTEM MODEL
This system is composed of three vital components R
statistical software to perform statistical analysis,
Hadoop framework to distribute data in the cluster
computing and Rhadoop that traverse over and link R
to Hadoop. Using this system, one can load
information from a local system to a hadoop library
through the hadoop distributed file system that reads
and analyses the input data. The four integral
elements that work together to associate R language
with hadoop are RAVRO, RMR, RHDFS, PLYRMR
& RHBASE.
The hadoop distributed file system that facilitates the
user to store, read, and write in hadoop distributed file
system. Given the inability of R in the statistical
analysis of massive information despite its excellent
performance with moderately sized data, when linked
with Hadoop, the resultant system is very promising
for several industries including stock market, artificial
intelligence designing and scientific research and
many more where business analytics need to be
performed.
Figure 1.1: System Model
3.1 Memory Management
Since apache hadoop is a cluster comprising of
several machines all performing on commodity
hardware, looking elsewhere for data storage is out of
question as it is simply possible to do horizontal
scaling of memory in each worker node or even the
master node.
The 2 challenges met with by R users due to its
constitutional property of reading memory by default
are
3.1.1 Reading data from Hadoop distributed file
system- Rhdfs and Rhbase both developed as parts of
the Rhadoop project helps researches using R, utilize
Hadoop hdfs and Hadoop base better. Of these,
Rhbase is what gives the cardinal connectivity to
hadoop distributed file systems. The tables in hbase
can be read, written and modified by a researcher
using R.
3.1.2. Computation Memory Management- Rhdfs
and by processing it either on the device or near it
reduces the area of conveyance. This is done in 2
steps
1. Map step: When a problem is assigned to a cluster,
the master nodes distributes it to smaller questions
and poses it to worker nodes that may distribute it to
smaller portions and distribute it among more nodes,
thereby creating a tree like pattern. When these
worker nodes come up with a solution, it is
transmitted back to the master node.
2. Reduce step: The solution s that are passed on to
the master node by the worker nodes are processed
into a single solution as required by the researcher.
As long as each mapping procedure is not intertwined
with another, parallelism is a possibility not conceived
yet due to the restrain in either the number of separate
storage systems or the number of CPUs in close
proximity to the operation site. And as long as
reduction procedures share the same key and are
submitted to the same reducer at the same time, a set
of reducers can perform the reduction phase with
ease.

Figure 1.2: MapReduce task of Wordcount
A petabyte of data can be processed by a cluster using
MapReduce. An advantage of the use of parallelism is
that an incomplete failure of server can be resolved if
the input data is still available, and even if one
mapper or reducer fails, the effort can be scheduled
for later.
4. RESULT AND DISCUSSION
The more concerning challenge has to deal with
massive data as R is constitutionally designed to read
the whole information in memory and scrutinize it all
to reach a solution when posed with a problem,
thereby creating 2 drawbacks that need be solved.
4.1 Data Memory Management
Depending on hardware configuration R objects can
occupy upto 2-4 GB exceeding which, the researcher
will be forced to use R and thereby analysis of big
data will have to be done. To overcome these
limitations, packages like ff[18], ffbase[18],
bigmemory[19] etc comes to play. Ff is a package that
stores large data efficiently on a disc that is quick to
access. However it can map only a portion of this data
n the main memory thereby acting as if in RAM and
sectioning the effective virtual memory consumption
per ff object. To raise performance standards to an
utmost, many improvising and simplifying approaches
like preprocessing and virtualization can be made use
of.
Ff packages could use external storage devices like
hard disk, CD, DVD etc to store binary files instead of
using it’s memory. It allows us to work on massive
data at one go by reading and writing file in a chunk.
The cost of increasing the memory of a system or
cluster is very high and thus it is more reasonable to
use R bearing in mind the fact that while performing
analysis, the entire data in memory will be taken into
consideration. Memory management is highly
efficient in R ff and ff base. But these packages are
compatible only with hadoop distributed file systems.
Figure 1.3: Working Mechanism of ff – package
Bigmemory, Biganalytics[20] and Biglm[21] are
programmes that can boost memory limitations.
Biganalytics has in it multiple analytic functions.
However ff is not compatible with hadoop and Biglm
that provides functions for linear regression is not
compatible with cluster systems.

with 3 Gb of RAM. The text file is a weather data of
one month with file size of 509 Mb and contain
4192912 rows and 44 columns. Assume if the file size
is 509 Mb for one month then it’ll be around
509*12Mb for 1 year. Definitely, people want to
perform analysis in data of entire year and even for
decade too. To perform analysis of large file is
possible using these packages but it is not good
practice when file size reach to terabytes and
petabytes and working with single node to perform
analysis where vertical scaling of memory is limited.
5. CONCLUSION AND FUTURE WORK
With the help of data memory management and
computational memory management techniques
handling large scale information has taken a new turn
by utterly changing memory requirement. The hurdles
in the processing of large data have thus been
decreased. Neither are we forced to deal with an
inappropriate random sample and compromise over an
incorrect statistical result, nor are we forced with the
limitation of vertical scaling that has a dead end. With
the addition of kmean, correlation, market basket,
time series and other such functionalities, the above
discussed model becomes all the more potent. By
combining opensource R and opensource Apache
hadoop, a cluster attains the marvel that only a
crossover between a cluster framework package and a
highly competent statistical programming language
can achieve. The security, availability, efficiency and
scalability it promises cannot be compared to
traditional database systems. when additional
programs like business intelligence or a link up with
systems like oracle or SAP will without doubt make it
the best analytic tool available in the industry. It
would also prove useful if in future the cluster could
maintain its optimization with a lesser number of
worker odes. In today’s hyper competitive world
where time is money if we can turn to cloud based big
data analytics when vital analysis needs to be
performed in a short time, big wealth too can be
sapped in a short time.
