HIVE-629. Concat files for map-reduce jobs. (Namit Jain via zshao)
Description
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.
