[jira] [Created] (FLINK-15087) JobManager is forced to shutdown JVM
due to temporary loss of zookeeper connection
Abdul Qadeer created FLINK-15087:
------------------------------------
Summary: 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
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:
