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
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.
