Description

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.
