------------------------------------------
+1. [~vikram.dixit] hive-14?
> Hive query fails after Tez session times out
> --------------------------------------------
>
> Key: HIVE-7857
> URL: https://issues.apache.org/jira/browse/HIVE-7857
> Project: Hive
> Issue Type: Bug
> Components: Tez
> Affects Versions: 0.14.0
> Reporter: Vikram Dixit K
> Assignee: Vikram Dixit K
> Priority: Critical
> Fix For: 0.14.0
>
> Attachments: HIVE-7857.1.patch, HIVE-7857.2.patch, HIVE-7857.3.patch

> Originally reported by [~deepesh]
> Steps to reproduce:
> Open the Hive CLI, ensure that HIVE_AUX_JARS_PATH has hcatalog-core.jar
> in the path.
> Keep it idle for more than 5 minutes (this is the default tez session
> timeout). Essentially Tez session should time out.
> Run a Hive on Tez query, the query fails. Here is a sample CLI session:
> {noformat}
> hive> select from_unixtime(unix_timestamp(), "dd-MMM-yyyy") from
> vectortab10korc limit 1;
> Query ID = hrt_qa_20140626002525_6e964079-4031-406b-85ed-cda9c65dca22
> Total jobs = 1
> Launching Job 1 out of 1
> Tez session was closed. Reopening...
> Session re-established.
