About Course

The field of Big Data is exploding with each passing day - new software tools and technologies enabling us to answer questions that we may not have been able to, even a few years ago. Its impact has been felt in almost every sphere of life - from transportation, health, education, commerce, communications and politics - to name a few! Hadoop has probably emerged as one of the most popular framework that enables huge data to be stored and processed. The tools that have been developed around Hadoop like Pig, Hive, Sqoop, Oozie, Flume and HBase - to name a few have allowed engineers to put Hadoop to great use - using the tools/languages that they are familiar with. Spark is a recent development. With its ability to process streaming data and allow machine learning algorithms to easily be applied on massive data, it is becoming the standard framework that developers what to learn and work with. This course will cover in detail various aspects of how Hadoop works. It also introduces you to Spark.

Course Objectives

At the end of the course you will be able to

  • Define Big Data and understand Data Engineering and Data Science concepts and roles
  • Understand Hadoop Architecture and be able to develop Map Reduce Programs using an IDE like Eclipse and Java
  • Use tools like Pig, Hive, Sqoop and HBase to store, query and process data residing in HDFS
  • Understand the limitations of Hadoop and get to know where Spark shines.
