--------------------------------
Assignee: (was: Todd Lipcon)
I gave up on this. See HIVE-21682 for some details on why.
> Parallel queries to HS2/Tez not thread safe (local mode)
> --------------------------------------------------------
>
> Key: TEZ-3420
> URL: https://issues.apache.org/jira/browse/TEZ-3420
> Project: Apache Tez
> Issue Type: Bug
> Affects Versions: 0.8.4
> Environment: HiveServer2 1.2.1 Local mode + Tez
> Reporter: Uday Chitragar
> Priority: Major
> Attachments: hive.log.submit.gz
>
>
> When running parallel queries (simultaneous connections by two beeline
> clients to HS2), I get the following exception (full debug attached),
> interestingly running the queries one after the other completes without any
> problem. The partition location and actual files seem to get mixed up across
> the DAGS
>
> The setup is Hive (1.2.1) and Tez (0.8.4) running in local mode.
