------------------------------------------
Summary: NodeManager Health Summary UNKNOWN from Standby
ResourceManager
Key: AMBARI-14275
URL: https://issues.apache.org/jira/browse/AMBARI-14275
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.1.1
Reporter: Vitaly Brodetskyi
Assignee: Vitaly Brodetskyi
Fix For: 2.3.0
PROBLEM: With YARN ResourceManager HA enabled, some of the
ResourceManager-related Ambari Alerts show UNKNOWN for the Standby RM. This is
misleading, because the state should be known (and likely OK, assuming that the
Standby RM is working correctly and redirecting to the Active one).
