What is Big Data?

• Big data is the term for a collection of data
  sets so large and complex that it becomes
  difficult to process using on-hand database
  management tools or traditional data processing
  applications.

4
Types of Big Data ?
Semi-Structured Data
Traditional RDBMS deals with only Structured data.
Need of a technology which deals with
Semi-structured data, Unstructured data and
Structured data as well
5
The 3Vs of Big Data
6
Sources of Data
Mobile Devices (Tracking all the objects all the
time)
Social Media Networks (All of us are generating
data)
Sensor Technology Networks (Measuring all kinds
of data)
Scientific Instruments (Collecting all sorts of
data)
7
Where Big Data is used ?
8
Facebook Scenario

Facebook on an average generates 70 thousand MB
in 1 minute.
1 hour 70,000 MB 60 4.2 Million
MB 1 Day 4.2 Million 24 MB 10.8
Billion MB 98438 GB 1 week 6.9 thousand
GB 690 TB 4 weeks 690 TB 4 2756 TB
2.7 PB 52 weeks 2.7 PB 52 143.3 PB
And thats aloooooooooot of data !

What is Hadoop ?
Hadoop was created by Doug Cutting and Mike
Cafarella. Hadoop provides the reliable shared
storage and analysis system. It is designed to
scale up from a single server to thousand of
machines, with a high degree of fault
tolerance.

Hadoop History
15
Hadoop Core Components

• Core Hadoop has two main systems
• Hadoop Distributed File System The Hadoop file
  system is a Distributed file system which holds
  the large amount of data across multiple nodes in
  a cluster.
• MapReduce MapReduce is a distributed programming
  paradigm used to analyze the data in the HDFS. 

16
Hadoop Distributed File System (HDFS)

• A given file is broken down into blocks
  (default64MB), then blocks are replicated
  across cluster (default3).
• Optimized for throughput.
• HDFS allows you to put/get/delete files.
• Follows the philosophy
• Write Once and Read Multiple times
• Block Replication for
• - Durability, High Availability and
  Throughput.

MapReduce Flow
18
MapReduce Framework
Map Reduce works by breaking the processing into
two phases Map Phase and Reduce Phase.
