Subject [jira] [Commented] (YARN-3692) Allow REST API to set a user generated message when killing an application
Date Thu, 21 May 2015 18:08:19 GMT

    [ https://issues.apache.org/jira/browse/YARN-3692?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14554764#comment-14554764
] 

Rajat Jain commented on YARN-3692:
----------------------------------

Yes. The user should be able to set a diagnostic message while killing the job. Usually this
helps in workflow management in a multi-tenant environment when the workflow scheduler (or
the hadoop admin) wants to kill a job - and let the user know the reason why the job was killed.
Killing the job by setting a diagnostic message is a very good solution for that. Ideally,
we can set the diagnostic message on all such interface:

  * yarn kill -applicationId ... -diagnosticMessage "some message added by admin/workflow"
  * REST API
    { 'state': 'KILLED', 'diagnosticMessage': 'some message added by admin/workflow'}

> Currently YARN's REST API supports killing an application without setting a diagnostic
message. It would be good to provide that support.
