Course Description

Hadoop is a framework written in Java for running applications on large clusters of commodity hardware. In this course we will examine many of the HDFS administration and operational processes required to operate and maintain a Hadoop cluster. We will take a look at how to balance a Hadoop cluster, manage jobs, and perform backup and recovery for HDFS. This learning path can be used as part of the preparation for the Cloudera Certified Administrator for Apache Hadoop (CCA-500) exam.
