[jira] [Commented] (FLINK-11914) Expose a REST endpoint in JobManager to kill specific TaskManager

    [ https://issues.apache.org/jira/browse/FLINK-11914?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17227308#comment-17227308 ] 

Matthias commented on FLINK-11914:
----------------------------------

Hi [~suez1224], I visited this issue as part of the backlog grooming of the Engine team and realized that it's idling for some time now. It looks like there is no need for this feature for now. Hence, I would close it if there's no objection from your side against it.

> we want to add capability in the Flink web UI to kill each individual TM by clicking a button, this would require first exposing the capability from the REST API endpoint. The reason is that  some TM might be running on a heavily loaded YARN host over time, and we want to kill just that TM and have flink JM to reallocate a TM to restart the job graph. The other approach would be restart the entire YARN job and this is heavy-weight.
