Hadoop Developer Foundations Course Details:

Apache Hadoop is a framework for processing Big Data, and Spark is a new in-memory processing engine. This course will introduce you to the Hadoop ecosystem and Spark.

This course explores processing large data streams in the Hadoop ecosystem. Working in a hands-on learning environment, you’ll learn techniques and tools for ingesting, transforming, and exporting data to and from the Hadoop ecosystem for processing. You’ll also process data using Map/Reduce and other critical tools, including Hive and Pig. Towards the end of the course, we’ll review other useful tools such as Oozie and discuss security in the ecosystem.
