SaintBacchus commented on SPARK-4694:
-------------------------------------
The reason was that Yarn had reported the status to the RM and the
YarnClientSchedulerBackend would detect the status to stop sc in function
'asyncMonitorApplication'.
But the HiveThriftServer2 is a long-run user thread. JVM will never exit until
all the no-demo threads have ended or using System.exit().
It cause such problem.
The easiest way to reslove this problem is using System.exit(0) instead of
sc.stop in funciton 'asyncMonitorApplication' .
But system.exit is not recommended in
https://issues.apache.org/jira/browse/SPARK-4584
Do you have any ideas about this problem? [~vanzin]

> Project: Spark
> Issue Type: Bug
> Components: YARN
> Reporter: SaintBacchus
>
> Recently when I use the Yarn HA mode to test the HiveThriftServer2 I found a
> problem that the driver can't exit by itself.
> To reappear it, you can do as fellow:
> 1.use yarn HA mode and set am.maxAttemp = 1for convenience
> 2.kill the active resouce manager in cluster
> The expect result is just failed, because the maxAttemp was 1.
> But the actual result is that: all executor was ended but the driver was
> still there and never close.
