This document provides information about J.Ayeesha Parveen, her class details, and incharge staff. It then summarizes Apache Hadoop, an open-source software framework for distributed storage and processing of large datasets. Key aspects of Hadoop include its distributed file system (HDFS), MapReduce processing model, and various components like NameNode, DataNodes, JobTracker, and TaskTracker. Common uses of Hadoop include analytics of audio, video, and log files.
This presentation discusses the following topics:
Hadoop Distributed File System (HDFS)
How does HDFS work?
HDFS Architecture
Features of HDFS
Benefits of using HDFS
Examples: Target Marketing
HDFS data replication
Comparison between RDBMS, Hadoop and Apache based on parameters like Data Variety, Data Storage, Querying, Cost, Schema, Speed, Data Objects, Hardware profile, and Used cases. It also mentions benefits and limitations.
Apache Hadoop software library is essentially a framework that
allows for the distributed processing of large data-sets across
clusters of computers using a simple programming model.

The data management industry has matured over the last three decades, primarily based on relational database management system(RDBMS) technology. Since the amount of data collected, and analyzed in enterprises has increased several folds in volume, variety and velocityof generation and consumption, organisations have started struggling with architectural limitations of traditional RDBMS architecture. As a result a new class of systems had to be designed and implemented, giving rise to the new phenomenon of “Big Data”. In this paper we will trace the origin of new class of system called Hadoop to handle Big data.
Big Data is a collection of large and complex data sets that cannot be processed using regular database management tools or processing applications. A lot of challenges such as capture, curation, storage, search, sharing, analysis, and visualization can be encountered while handling Big Data. On the other hand the Apache Hadoop software library is a framework that allows for the distributed processing of large data sets across clusters of computers using simple programming models. It is designed to scale up from single servers to thousands of machines, each offering local computation and storage. Big Data certification is one of the most recognized credentials of today.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

2. Apache Hadoop is an open-source software
framework for storage and large-scale
processing of data-sets on clusters of
commodity hardware.
Hadoop is best known for MapReduce and its
distributed filesystem (HDFS),and large-scale
data processing.
4. Introduction to the world of Hadoop and the
core related software projects.
There are countless commercial Hadoop-
integrated products focused on making
Hadoop more usable and layman-accessible,
but the ones here were chosen because they
provide core functionality and speed in
Hadoop so called Hadoop Ecosystem
9. NameNode:
Master of the system
Maintains and manages the blocks which are present on
the DataNodes
DataNodes:
Slaves which are deployed on each machine and
provide the actual storage
Responsible for serving read and write requests for the
clients
Jobtracker:
takes care of all the job scheduling and assign tasks to
Task Trackers.
TaskTracker:
a node in the cluster that accepts tasks - Map, Reduce
and Shuffle operations - from a jobtracker
10. Hadoop Distributed File System (HDFS) is designed
to reliably store very large files across machines in
a large cluster. It is inspired by the
GoogleFileSystem.
Distribute large data file into blocks
Blocks are managed by different nodes in the
cluster
Each block is replicated on multiple nodes
Name node stored metadata information about files
and blocks
11. The Mapper:
Each block is processed in isolation by a map task
called mapper
Map task runs on the node where the block is stored
The Reducer:
Consolidate result from different mappers
Produce final output
12. Hbase-Hadoop database for random read/write
access
Hive-SQLlike queries and tables on large datasets
Pig-Data flow language and compiler
Oozie-Workflow for interdependent Hadoop jobs
Sqoop-Integration of databases and data
warehouses with Hadoop
Flume-Configurable streaming data collection
ZooKeeper-Coordination service for distributed
applications
13. Feature. RDBMS Hadoop
Data Variety Mainly for Structured data. Used for Structured, Semi-
Structured and Unstructured
data
Data Storage Average size data (GBS) Use for large data set (Tbs
and Pbs)
Querying SQL Language HQL (Hive Query Language)
Schema Required on write (static
schema)
Required on read (dynamic
schema)
Speed Reads are fast Both reads and writes are fast
Cost License Free
Use Case OLTP (Online transaction
processing)
Analytics (Audio, video, logs
etc), Data Discovery
Data Objects Works on Relational Tables Works on Key/Value Pair
Throughput Low High
Scalability Vertical Horizontal
Hardware Profile High-End Servers Commodity/Utility Hardware
Integrity High (ACID) Low
