Overview/Description
The Apache Hadoop software library is a framework that allows for the distributed processing of large datasets across clusters of computers using a simple programming model. Hadoop can scale up from single servers to thousands of machines, each offering local computation and storage. This course will focus on performance tuning of the Hadoop cluster. We will examine best practices and recommendations for performance tuning of the operating system, memory, HDFS, YARN and MapReduce. This learning path can be used as part of the preparation for the Cloudera Certified Administrator for Apache Hadoop (CCA-500) exam.

Target Audience
Administrators looking to expand their skill sets to include performance tuning Hadoop clusters

Prerequisites
None
