YARN and MapReduce 2: An Overview
At their core, YARN and MapReduce 2’s improvements separate cluster resource management capabilities from MapReduce-specific logic. YARN enables Hadoop to share resources dynamically between multiple parallel processing frameworks such as Cloudera Impala, allows more sensible and finer-grained resource configuration for better cluster utilization, and scales Hadoop to accommodate more and larger jobs.
This class offers an overview of YARN. We will cover YARN's motivation, its architecture, its implementation and its usage. We will also discuss MapReduce 2 and how it fits in with YARN.
