> 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.
