[jira] [Commented] (YARN-1734) RM should get the updated Configurations when it transits from Standby to Active

    [ https://issues.apache.org/jira/browse/YARN-1734?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13918272#comment-13918272 ] 

Karthik Kambatla commented on YARN-1734:
----------------------------------------

Sorry for jumping in late here.

It appears the AdminService#refreshAll is called on transition to active. However, calling any of the refresh commands on the Standby throws StandbyException. This can lead to confusion - we throw an exception even though the refresh command takes affect when the RM transitions to Active.

> Currently, we have ConfigurationProvider which can support LocalConfiguration, and FileSystemBasedConfiguration. When HA is enabled, and FileSystemBasedConfiguration is enabled, RM can not get the updated Configurations when it transits from Standby to Active
