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'} > Allow REST API to set a user generated message when killing an application > -------------------------------------------------------------------------- > > Key: YARN-3692 > URL: https://issues.apache.org/jira/browse/YARN-3692 > Project: Hadoop YARN > Issue Type: Improvement > Reporter: Rajat Jain > Assignee: Rohith > > Currently YARN's REST API supports killing an application without setting a > diagnostic message. It would be good to provide that support. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
