Big Data raises challenges about how to process such vast pool of raw data and how to aggregate value to our lives. For addressing these demands an ecosystem of tools named Hadoop was conceived.
Big Data and Hadoop training course is designed to provide knowledge and skills to become a successful Hadoop Developer. In-depth knowledge of concepts such as Hadoop Distributed File System, Setting up the Hadoop Cluster, Map-Reduce,PIG, HIVE, HBase, Zookeeper, SQOOP etc. will be covered in the course.
View the Big Data Technology Stack in a nutshell. This Big Data Technology Stack deck covers the different layers of the Big Data world and summarizes the major technologies in vogue today.
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.
Big data is a popular term used to describe the large volume of data which includes structured, semi-structured and unstructured
data. Now-a-days, unstructured data is growing in an explosive speed with the development of Internet and social networks like Twitter,Facebook
& Yahoo etc., In order to process such colossal of data a software is required that does this efficiently and this is where Hadoop steps in. Hadoop
has become one of the most used frameworks when dealing with big data. It is used to analyze and process big data. In this paper, Apache Flume

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

5. the origins of large data sets
go back to the 1960s and '70s
when the world of data was
just getting started with the
first data centers and the
development of the relational
database.
Around 2005, people began
to realize just how much data
users generated through
Facebook, YouTube, and
other online services.
NoSQL also began to gain
popularity during this time.
Users are still generating
huge amounts of data—but
it’s not just humans who are
doing it.With the advent of
the Internet of Things (IoT),
more objects and devices are
connected to the internet,
gathering data on customer
usage patterns and product
performance
ORIGIN

PRESENT
HISTORY OF BIG DATA
6. It has been organized into a formatted repository that is typically a
database. It concerns all data which can be stored in database SQL
in a table with rows and columns. Ex - Relational data
STRUCTURED DATA
Semi-structured data is information that does not reside in a
relational database but that have some organizational properties
that make it easier to analyze. Ex- XML , JSON etc.
SEMI - STRUCTURED DATA
Unstructured data is a data which is not organized in a predefined
manner or does not have a predefined data model
Ex - Word, PDF, Text, Media files etc.
UNSTRUCTURED DATA
TYPES OF BIG
DATA
7. Big data brings together
data from many disparate
sources and applications
raditional data integration
mechanisms, such as ETL
(extract, transform, and
load) generally aren’t up to
the task
Big data requires storage. Your
storage solution can be in the
cloud, on premises, or both.
The cloud is gradually gaining
popularity because it supports
your current compute
requirements and enables you
to spin up resources as needed

20. HADOOP HDFS
Data is stored in a distributed manner in HDFS. There are
two components of HDFS - name node and data node.
While there is only one name node, there can be multiple
data nodes.
Provides distributed storage
Can be implemented on commodity hardware
Provides data security
Highly fault-tolerant - If one machine goes down, the data
from that machine goes to the next machine
Features of HDFS
21. The major advantage of MapReduce is that it is easy to scale data
processing over multiple computing nodes.
MapReduce consists of two distinct tasks – Map and Reduce.
As the name MapReduce suggests, the reducer phase takes place
after the mapper phase has been completed.
the first is the map job, where a block of data is read and
processed to produce key-value pairs as intermediate outputs.
The reducer receives the key-value pair from multiple map jobs.
Then, the reducer aggregates those intermediate data tuples
(intermediate key-value pair) into a smaller set of tuples or key-
value pairs which is the final output.Let us understand more
about MapReduce and its components. MapR
HADOOP MAPREDUCE
Hadoop MapReduce is the processing unit of Hadoop. In
the MapReduce approach, the processing is done at the
slave nodes, and the final result is sent to the master node.
22. Hadoop YARN acts like an OS to Hadoop. It is a file system that is
built on top of HDFS.
It is responsible for managing cluster resources to make sure you
don't overload one machine.
It performs job scheduling to make sure that the jobs are
scheduled in the right place
HADOOP YARN
Hadoop YARN stands for Yet Another Resource Negotiator.
It is the resource management unit of Hadoop and is
available as a component of Hadoop version 2.
