Shuyi Chen commented on FLINK-11914:
------------------------------------
Hi [~feng.xu], I dont think we should expose an Akka endpoint because Akka is
an internal implementation detail, and AFAIK, the community is trying to
deprecate the use of Akka in Flink. Thanks.
> Expose a REST endpoint in JobManager to kill specific TaskManager

> 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.
