PROBLEM STATEMENT: There are frequent email alerts from HiveServer2 Metastore process which are misleading. When check the HiveServer2 Metastore process is up and running fine without issue.
ERROR: Below is sample email alert -
Ambari Alerts log output shows -
ROOT CAUSE: The issue was with kerberos credentials for ambari-qa user.
HiveServer2 Metastore alert is triggered from the node on which the service is installed. "ambari-qa" user is used by ambari to trigger the alert. If you are using kerberized cluster make sure you have "ambari-qa" ticket in place else false alert will be triggered.
