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

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