Review request for hive, Yongqiang He, Ning Zhang, and namit jain.
Summary
-------
By explicitely setting the two variable HIVEMERGEMAPFILES and
HIVEMERGEMAPREDFILES to false before compiling the query to build the index, it
guarantees that there will not be a merge task.
This addresses bug HIVE-2543.

Testing
-------
I ran an explain plan on a command to rebuild an index and verified it did not
contain a merge task.
I also verified all the index related tests still pass.
Thanks,
Kevin
