----------------------------------------
Summary: Various metrics show no data available - when HA enabled
Key: AMBARI-13641
URL: https://issues.apache.org/jira/browse/AMBARI-13641
Project: Ambari
Issue Type: Bug
Components: 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
