Thomas Scott commented on HIVE-14162:
-------------------------------------
This is equivalent to running:
set hive.execution.engine=spark;
<some hive query>
set hive.execution.engine=mr;
> Allow disabling of long running job on Hive On Spark On YARN
> ------------------------------------------------------------

> Key: HIVE-14162
> URL: https://issues.apache.org/jira/browse/HIVE-14162
> Project: Hive
> Issue Type: New Feature
> Components: Spark
> Reporter: Thomas Scott
> Priority: Minor
>
> Hive On Spark launches a long running process on the first query to handle
> all queries for that user session. In some use cases this is not desired, for
> instance when using Hue with large intervals between query executions.
> Could we have a property that would cause long running spark jobs to be
> terminated after each query execution and started again for the next one?
