Big Data Hadoop – Developer

Course number: BDHD-CGI001

What is Big Data?
Big Data is a term used to define data sets that have the potential to rapidly grow so large that they become unmanageable. The Big Data movement includes new tools and ways of storing information that allow efficient processing and analysis for informed business decision-making.

What is Hadoop?
Hadoop is an open source implementation of MapReduce by the Apache group and is the most widely used platform on which to solve problems in processing large, complex data sets that would otherwise be intractable using conventional means. It is a high performance distributed storage and processing system. Hadoop fills the gap in the market by effectively storing and providing computational capabilities for substantial amounts of data. There is commercial support from multiple vendors and prepackaged cloud solutions.

What is MapReduce?
MapReduce is a parallel programming model that allows distributed processing on large data sets on a cluster of computers. MapReduce was originally implemented by Google as part of their searching and indexing of the Internet. It has since grown in popularity and is quickly being adopted by most industries.

How are Hadoop programs developed?
Primarily programs are written in Java although Hadoop has facilities to handle programs written in other languages like C++, Python, and .NET. Programs can also be written in scripting languages like Pig. Data in HDFS can be queried using a SQL-like syntax with Hive.

What are the advantages of using Hadoop?
Hadoop provides the ability to process and analyze more data than was previously possible at a lower cost
It runs on scalable commodity clusters
It has self-healing capabilities to survive hardware failures
It operates on various types of data and adapts to meet varying degrees of structure
HDFS automatically provides robustness and redundancy for performance and reliability
There are many associated projects that enhance the Hadoop ecosystem and ease development

What is this course about?
The availability of large data sets presents new opportunities and challenges to organizations of all sizes. This course provides the hands-on programming skills to leverage the Apache Hadoop platform to efficiently process a variety of Big Data. Additionally, you learn to test and deploy Big Data solutions on commodity clusters. This course also covers Pig, Hive, HBase and other components of the Hadoop ecosystem. Further, this course teaches testing, deployment and best practices to architect and develop a complete Big Data solution.
