Review request for Ambari, Dmytro Sen, Sumit Mohanty, and Sid Wagle.
Bugs: AMBARI-15694
https://issues.apache.org/jira/browse/AMBARI-15694
Repository: ambari
Description
-------
When querying a large number of Hosts, AMS API returns a truncated set of
data-points. The number of data-points is
Metrics service default result limit / no. of hosts
If the Metrics service default result limit is set to 15840 (current default),
then for 900 hosts, the data-points that will be returned for each host will be
18.
FIX
Take into account the hostnames requested also, while calculating calculating
result set size estimate.
