Review request for Ambari, Dmytro Sen, Mahadev Konar, and Myroslav Papirkovskyy.
Bugs: AMBARI-13641
https://issues.apache.org/jira/browse/AMBARI-13641
Repository: ambari
Description
-------
The Metrics Cache introduced in Ambari stores the metrics result in an HashMap
with metric name as the key. This results in a problem when the same request
needs to fetch metrics for both the Namenodes or both the Resourcemangers. The
last result gets cached.
*Note*: Workaround for this is to disable cache in 2.1.2 by setting this
property in ambari.properties file : server.timeline.metrics.cache.disabled =
true
