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

             Summary: Expose a REST endpoint in JobManager to disconnect specific TaskManager
                 Key: FLINK-11914
                 URL: https://issues.apache.org/jira/browse/FLINK-11914
             Project: Flink
          Issue Type: New Feature
          Components: Runtime / REST
            Reporter: Shuyi Chen
            Assignee: Shuyi Chen


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.
