Rohit Agarwal commented on HIVE-10569:
--------------------------------------
It will work fine if tez is configured properly - if tez is not configured
properly, instead of printing an exception and showing the prompt (so that I
can run another query) - it prints an exception and gets stuck (no prompt.)
> Hive CLI gets stuck when hive.exec.parallel=true; and some exception happens
> during SessionState.start

> 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}}
