Course description
Hadoop Developer Foundation | Explore Hadoop, HDFS, Hive, Yarn & More
Hadoop Developer Foundation | Working with Hadoop, HDFS, Hive, Yarn, Spark and More explores processing large data streams in the Hadoop Ecosystem. Working in a hands-on learning environment, students will learn techniques and tools for ingesting, transforming, and exporting data to and from the Hadoop Ecosystem for processing, as well as processing data using Map/Reduce, and other critical tools including Hive and Pig. Towards the end of the course, we’ll introduce other useful tools such as Spark and Oozie and discuss essential security in the ecosystem.
This “skills-centric” course is about 50% hands-on lab and 50% lecture, designed to train attendees in core big data/ Spark development and use skills, coupling the most current, effective techniques with the soundest industry practices. Throughout the course students will be led through a series of progressively advanced topics, where each topic consists of lecture, group discussion, comprehensive hands-on lab exercises, and lab review.
