Subject [jira] [Commented] (YARN-3692) Allow REST API to set a user generated message when killing an application

-----------------------------------------

Thanks [~aw] for the reply
Just one confirmation, i can understand if jenkins is not able to catch the test case failure
outside the project where patch modifications are done, but here i felt compilation error
was not getting detected for other projects. so it would not count as compatability but compilation
failure. Correct me if i am wrong or am i missing something here ?

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