Review request for Ambari, Dmytro Sen, Sumit Mohanty, and Sid Wagle.
Bugs: AMBARI-20913
https://issues.apache.org/jira/browse/AMBARI-20913
Repository: ambari
Description
-------
PROBLEM
On a 4 node LLAP cluster grafana "LLAP Overview" dashboard shows incorrect
data. The metric seems to have been multiplied by a factor of 10.
BUG
This issue had been fixed in the V2 aggregation mechanism (Phoenix server side
aggregation) through AMBARI-15638. It was missed out on the V1 mechanism of
aggregation where the data is read into the Metrics Collector and manual client
side aggregation is done.
