This issue is caused by two job engine scheduling the same one job.
From logs, we can see
* at 08:07:42.106, kylin-all-0 released the lock
* at 08:07:42.132, kylin-job-0 acquired the lock
* at 09:56:37.774, kylin-all-0 tried to update job status because it was not aware it had lost the lock. Then error occurs.
The reason kylin-all-0 released the lock is because it was going through "Full GC"
