Subject [jira] [Commented] (HIVE-14162) Allow disabling of long running job on Hive On Spark On YARN
Date Tue, 15 Nov 2016 17:13:58 GMT

    [ https://issues.apache.org/jira/browse/HIVE-14162?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15667691#comment-15667691

Thomas Scott commented on HIVE-14162:
-------------------------------------

[~aihuaxu][~xuefuz] if i remember correctly the case in particular here was from Hue. Hue
starts  long running sessions that cannot be easily killed by the Hue user. The work around
was to switch execution engines before and after executing queries but this is far from intuitive.

> 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?
