Review request for Ambari, Dmytro Sen, Sumit Mohanty, and Sid Wagle.
Bugs: AMBARI-18593
https://issues.apache.org/jira/browse/AMBARI-18593
Repository: ambari
Description
-------
HDFS exposes top user activity broken down by operations in jmx (nntop).
These metrics should be captured in AMS and exposed in Grafana's HDFS
dashboards.
Downsampling should likely be a function like MIN, MAX, AVG, SUM of underlying
timeseries specified from the client.
