Subject [jira] [Updated] (YARN-6304) Skip rm.transitionToActive call to RM if RM is already active.
Date Fri, 10 Mar 2017 07:53:04 GMT

     [ https://issues.apache.org/jira/browse/YARN-6304?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Rohith Sharma K S updated YARN-6304:
------------------------------------
    Description: 
When elector elects RM to become active, even though RM is already in ACTIVE state AdminService
does refresh on following configurations. 
# refreshAdminAcls 
# refreshAll to update the configurations.

But ideally even these operations are need NOT to be done and can be skipped refreshing configurations
on ACTIVE RM. However admin executes refresh command separately if there is any config changes
to be done.

#. refreshAdminAcls 
# refreshAll to update the configurations.

I think we can skip refreshing configurations on ACTIVE RM. However admin executes refresh
command separately which indicates him failure if any.
