> We face a problem when we try to use flink on k8s to execute task with
> udf/udtf. When we finished or canceled a job and submit a same job, the old
> TM will be not reachable and restart. Why the TM have to be restart? In
> session mode, the TM should be reused by JM. Moreover, if we off restart
> strategy, this task will fail.
