Subject [jira] [Commented] (YARN-2209) Replace allocate#resync command with ApplicationMasterNotRegisteredException to indicate AM to re-register on RM restart
Date Wed, 25 Jun 2014 21:49:24 GMT

    [ https://issues.apache.org/jira/browse/YARN-2209?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14044096#comment-14044096
] 

Vinod Kumar Vavilapalli commented on YARN-2209:
-----------------------------------------------

Makes sense. We need to be consistent across allocate/unregister calls. For things like shut-down
and resync, I prefer exceptions. We can deprecate the corresponding AMCommands.

> Replace allocate#resync command with ApplicationMasterNotRegisteredException to indicate
AM to re-register on RM restart
