Subject [jira] [Commented] (YARN-1734) RM should get the updated Configurations when it transits from Standby to Active
Date Tue, 04 Mar 2014 05:24:22 GMT

    [ https://issues.apache.org/jira/browse/YARN-1734?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13919031#comment-13919031

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

Sorry for all the confusion caused here - forgot that the rmadmin command also uses ConfiguredRMFailoverProxyProvider.

Played with a cluster with local configurations. It behaves as expected. refresh* refreshes
the Active. The Standby refreshes everything on transition to active. Thanks [~xgong] for
fixing the refresh commands, and for being patient with my questions/concerns.

> 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
