> Consider the following set of queries:
> ALTER TABLE abc ADD PARTITION (x='0') LOCATION 'file:///foo';
> ALTER TABLE abc ADD PARTITION (x='1') LOCATION '/foo';
> select count(*) from abc;
> Even though there are different files under these directories, depending on number of
mappers, the count produces a value = num of mappers * num of files in the 2 directories.
This is incorrect.
