Yongming Zhang commented on FLINK-30505:
----------------------------------------
If the termination of the pod is caused by TM being unreachable,the first
exception thrown is tm unreachable,this does not mislead users.On the other
hand, close the connection between task executor and job master when resource
manager detects a task executor has failed,jobs can failover earlier.
> Close the connection between TM and JM when task executor failed
