Subject [jira] [Commented] (YARN-1734) RM should get the updated Configurations when it transits from Standby to Active
Date Mon, 03 Mar 2014 19:10:27 GMT

    [ https://issues.apache.org/jira/browse/YARN-1734?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13918441#comment-13918441

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

bq. For calling refresh* in standby RM, it will throw a standbyException and trigger the retry.
In that case, even if we call refresh* in Standby RM, it actually do the refresh* in active
RM.
Sorry, I missed this while browsing through the code. Let me try this on a cluster and report.

> 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
