[jira] [Created] (FLINK-8462) TaskExecutor does not verify RM heartbeat timeouts

Till Rohrmann created FLINK-8462:
------------------------------------

             Summary: TaskExecutor does not verify RM heartbeat timeouts
                 Key: FLINK-8462
                 URL: https://issues.apache.org/jira/browse/FLINK-8462
             Project: Flink
          Issue Type: Bug
          Components: Distributed Coordination
    Affects Versions: 1.5.0
            Reporter: Till Rohrmann
            Assignee: Till Rohrmann
             Fix For: 1.5.0


The {{TaskExecutor}} does neither properly stop RM heartbeats nor does it check whether a RM heartbeat timeout is still valid. As a consequence, it can happen that the {{TaskExecutor}} closes the connection to an active {{RM}} due to an outdated heartbeat timeout.
