---------------------------------
I will change the name of the parameter and regenerate the patch.
> concat files needed for map-reduce jobs also
> --------------------------------------------

> Key: HIVE-629
> URL: https://issues.apache.org/jira/browse/HIVE-629
> Project: Hadoop Hive
> Issue Type: Improvement
> Components: Query Processor
> Affects Versions: 0.4.0
> Reporter: Namit Jain
> Assignee: Namit Jain
> Attachments: hive.629.1.patch

>
> Currently, hive concatenates files only if the job under consideration is a
> map-only job.
> I got some requests from some users, where they want this behavior for
> map-reduce jobs also - it may not be a good idea to turn it on by default.
> But, we should provide an option to the user where the concatenation can
> happen even for map-reduce jobs.
