> Key: AMBARI-13641
> URL: https://issues.apache.org/jira/browse/AMBARI-13641
> Project: Ambari
> Issue Type: Bug
> Components: ambari-metrics, ambari-server
> Affects Versions: 2.1.2
> Reporter: Siddharth Wagle
> Assignee: Siddharth Wagle
> Priority: Critical
> Fix For: 2.1.3

> 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
