Chengbing Liu updated HIVE-7590:
--------------------------------
Affects Version/s: 0.14.0
> Should not fire a merge job if
> hive.hadoop.supports.splittable.combineinputformat is set to false
> -------------------------------------------------------------------------------------------------
>
> Key: HIVE-7590
> URL: https://issues.apache.org/jira/browse/HIVE-7590
> Project: Hive
> Issue Type: Bug
> Components: Query Processor
> Affects Versions: 0.10.0, 0.14.0
> Reporter: Chengbing Liu
> Attachments: HIVE-7590.patch
>
>
> When hive.hadoop.supports.splittable.combineinputformat is set to false, a
> map can process only one file, making the merge job not actually doing
> merging. The merge job should only be fired if
> hive.hadoop.supports.splittable.combineinputformat is set to true.
> I have observed this with 0.10. It seems trunk also has this problem.
