Get Started with BIG Data & Hadoop

Big Data and its Challenges

Big Data and its Challenges
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
Systems / Enterprises generate huge amount of
data from Terabytes to and even Petabytes of
information
It’s very difficult to manage such huge data……

Who Generates Big Data?
Have you ever wondered how Google, Facebook or LinkedIn manages to store and utilize the huge data?
Today, managing unstructured and voluminous data is creating a big problem.Get Started with BIG Data & Hadoop

Hadoop can be utilized for processing & analyzing large data-sets.
Before that let’s understand what is Hadoop?

Hadoop and its Characteristics
Apache Hadoop is a framework that allows the distributed processing of large data sets across clusters of
commodity computers using a simple programming model
It is an Open-source Data Management technology with scale-out storage and distributed processing

Hive Origination
ᗍ Hive originated as an internal project in Facebook
ᗍ Later it was adopted in Apache as an open source project
ᗍ Facebook deals with massive amount of data (petabytes scale) and it needs to perform more than
75k ad-hoc queries on this massive amount of data
ᗍ Since the data is collected from multiple servers and is of diverse nature, any RDBMS system could
not fit as probable solution
ᗍ Map Reduce could be a natural choice, but it had its own limitations

What is Hive?
ᗍ It is a query engine wrapper built on top of Map Reduce
ᗍ It is treated as Data Warehousing tool of Hadoop Ecosystem
ᗍ It is used for data analysis
ᗍ Primarily targeted to the users with SQL background
ᗍ Provides HiveQL, which is very similar to SQL
ᗍ It is used for managing and querying structured data
ᗍ Hadoop complexity is hidden from end users
ᗍ Java and Hadoop API knowledge is optional for core users
ᗍ Developed by Facebook and contributed to community
