StartExecutionOperation invocation failed to complete due to operation-heartbeat-timeout.

[Lukáš Herman]

Hello Jet Team,

we have noticed that during certain failure scenarios, when a node becomes unresponsive for several minutes, all jobs are terminated with OperationTimeoutException: StartExecutionOperation invocation failed to complete due to operation-heartbeat-timeout right after a cluster is formed from remaining members. 

Is this expected behavior? Because we have already seen and tested scenarios with topology changes where the jobs were restarted automatically. 

(Jet 0.7.2)

Hi Lukáš,

Please see this PR: 

https://github.com/hazelcast/hazelcast-jet/pull/1377

Previously the timeout wasn't being treated as a restarable exception, but after this PR they should be treated as restartable exceptions. This was merged into 3.1.
