Review request for Ambari, Dmytro Sen, Sumit Mohanty, and Sid Wagle.
Bugs: AMBARI-16440
https://issues.apache.org/jira/browse/AMBARI-16440
Repository: ambari
Description
-------
HBase Regionserver daemons shuts down and restarts the Metric System for every
5 minutes to make sure there is no growth of metrics. This causes AMS Hadoop
sink to lose metrics intermittently, which was buffered during that time. This
leads to holes in data and negative rates in graphs.
