> JobManager is forced to shutdown JVM due to temporary loss of zookeeper
> connection
> ----------------------------------------------------------------------------------
>
> Key: FLINK-15087
> URL: https://issues.apache.org/jira/browse/FLINK-15087
> Project: Flink
> Issue Type: Bug
> Affects Versions: 1.8.2
> Reporter: Abdul Qadeer
> Priority: Major
>
> While testing I found that the loss of connection with zookeeper triggers JVM
> shutdown for Job Manager, when started through
> "StandaloneSessionClusterEntrypoint". This happens due to a NPE on
> "taskManagerHeartbeatManager."
> When JobManagerRunner suspends jobMasterService (as Job manager is no longer
> leader), "taskManagerHeartbeatManager" is set to null in
> "stopHeartbeatServices".
> Next, "AkkaRpcActor" stops JobMaster and throws NPE in the following method:
> {code:java}
> @Override
> public CompletableFuture<Acknowledge> disconnectTaskManager(final ResourceID
> resourceID, final Exception cause) {
> log.debug("Disconnect TaskExecutor {} because: {}", resourceID,
> cause.getMessage());
> taskManagerHeartbeatManager.unmonitorTarget(resourceID);
> slotPool.releaseTaskManager(resourceID, cause);
> {code}
>
> This leads to a fatal error finally in "ClusterEntryPoint.onFatalError()" and
> forces JVM shutdown.
> The stack trace is below:
