--------------------------------------

It seems to be the same problem as FLINK-13554.
But I cannot confirm that since there's only JM INFO logs.

> As in the attached JM log, the job tried to start 30 TMs but only 29 are registered. So the job fails due to not able to acquire all 30 slots needed in time.
> And when the failover happens and tasks are re-scheduled, the RM will not ask for new TMs even if it cannot fulfill the slot requests. So the job will keep failing for slot allocation timeout.
