llap0 app (was: HiveServer2 Interactive LLAP reconnect to already running Yarn
app)
> HiveServer2 Interactive LLAP (re)connect to already running Yarn llap0 app
> --------------------------------------------------------------------------
>
> Key: HIVE-20666
> URL: https://issues.apache.org/jira/browse/HIVE-20666
> Project: Hive
> Issue Type: Improvement
> Components: HiveServer2, llap
> Affects Versions: 1.2.1
> Reporter: Hari Sekhon
> Priority: Major
>
> Improve HiveServer2 Interactive LLAP to (re)connect to already running hive
> llap yarn app.
> Currently HiveServer2 Interactive startup may fail with the following error
> if it cannot get enough containers on the queue:
> {code:java}
> WARN cli.LlapStatusServiceDriver: Watch timeout 200s exhausted before desired
> state RUNNING is attained.
> 2018-10-01 16:26:55,624 - LLAP app 'llap0' in 'RUNNING_PARTIAL' state. Live
> Instances : '3'. Desired Instances : '4' after 212.498996019 secs.
> 2018-10-01 16:26:55,624 - App state is RUNNING_PARTIAL. Live Instances : '3',
> Desired Instance : '4'
> 2018-10-01 16:26:55,624 - LLAP app 'llap0' deployment unsuccessful.
> 2018-10-01 16:26:55,625 - Stopping LLAP
> 2018-10-01 16:26:55,625 - call[['slider', 'stop', u'llap0']] {'logoutput':
> True, 'user': 'hive', 'stderr': -1}{code}
> I could meanwhile see 5 containers for a previous hive llap invocation in the
> yarn scheduler page and this is the only HiveServer2 Interactive instance, so
> it appears it wasn't (re)connecting and making use of the running llap app.
> It's also possible that the containers were simply slow to allocate as the
> cluster was operating at 100% capacity and therefore weren't fully
> initialized when the app failed, but the error feedback doesn't give enough
> details about the state of the llap0 app.
