Description

Out of disk space issues are seen due to the sheer amount of logs being produced by hive after addition of metrics. For this, a single change needs to be done to the log4j properties offered by Ambari to fix this.

In hive-log4j content, the following needs to be added.

# Silence HadoopMetrics2Reporter INFO logs
log4j.logger.com.github.joshelser.dropwizard.metrics.hadoop=WARN,DRFA

This upgrade jira is only for adding the log level changes for Hive components part of HDP 2.4 stack. Hive components that have been added in HDP2.5 fall into the category of either not needing this change or using default from stack.
