Description
The SourceCoordinator currently forwards all exceptions from `Source#createEnumerator` up the stack triggering a JobMaster failover. However, JobMaster failover only works if HA is enabled[1]. If HA is not enabled the fatal error handler will simply exit the JM process killing the entire cluster. This is problematic in the case of a session cluster where there may be multiple jobs running. It also does not play well with external tooling that does not expect job failure to cause a full cluster failure.
It would be preferable if failure to create an enumerator did not take down the entire cluster, but instead failed that particular job.
