Summary
-------
alter table concatenate fails and deletes data
It is because the number of reducers is set to -1.
In this patch, it is set to zero.
Also added a move task as the child task of the merge task. added a conf to
control whether to check index or not, and add the job name for the merge job.
This addresses bug HIVE-2125.
