AlexHu updated FLINK-30244:
---------------------------
Description:
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.
