Alexander Pivovarov commented on HIVE-10569:
--------------------------------------------
I tried this with hive-0.13.1. The query works fine for me
{code}
hive> set hive.exec.parallel=true;
hive> set hive.execution.engine=tez;
hive> create table sometable(somecol INT);
OK
Time taken: 3.363 seconds
hive> select count(*) from sometable;

> Hive CLI gets stuck when hive.exec.parallel=true; and some exception happens

> Key: HIVE-10569
> URL: https://issues.apache.org/jira/browse/HIVE-10569
> Project: Hive
> Issue Type: Bug
> Affects Versions: 0.13.1, 1.1.0
> Reporter: Rohit Agarwal
> Priority: Critical
> Attachments: HIVE-10569.patch
>
>
> The CLI gets stuck in the loop in [DriverContext.pollFinished |
> https://github.com/apache/hive/blob/release-1.1.0/ql/src/java/org/apache/hadoop/hive/ql/DriverContext.java#L108]
> when some {{TaskRunner}} which has completed has not been marked as
> non-running.
> This can happen when there is exception in [SessionState.start |
> https://github.com/apache/hive/blob/release-1.1.0/ql/src/java/org/apache/hadoop/hive/ql/exec/TaskRunner.java#L74]
> which is called from {{TaskRunner.run}}.
> This happened with us when we were running with {{hive.exec.parallel=true}},
> {{hive.execution.engine=tez}} and Tez wasn't correctly setup.
> In this case the CLI printed the exception and then got hung (No prompt.)
> A simple fix is to call {{result.setRunning(false);}} in the {{finally}}
> block of {{TaskRunner.run}}
