Sergey Shelukhin resolved HIVE-10692.
-------------------------------------
Resolution: Cannot Reproduce
> LLAP: DAGs get stuck at start with no tasks executing
> -----------------------------------------------------

> Key: HIVE-10692
> URL: https://issues.apache.org/jira/browse/HIVE-10692
> Project: Hive
> Issue Type: Sub-task
> Reporter: Sergey Shelukhin
> Assignee: Siddharth Seth

> Internal app ID application_1429683757595_0914, LLAP
> application_1429683757595_0913. If someone without access wants to
> investigate I'll get the logs.
> 2nd dag failed to start executing:
> See syslog_dag_1429683757595_0914_2 log file.
> This happened to me a couple of times today, didn't see it before.
> After many S_TA_LAUNCH_REQUEST-s, the following is logged and after that
> there's no more logging aside from refreshes until I killed the DAG. LLAP
> daemons were idling meanwhile.
> I don't see any errors (aside from ATS) before this happened
