Insert Overwrite of a full ACID table when the select returns no data is not creating an empty base dir.

insert overwrite table dest_acid select * from src;

If src has no data, we should still create an empty base directory in dest_acid so that readers get no data to read. This is not happening right now as we do not create such an empty base dir.

Is my understanding correct ekoifman gopalv vgumashta ?
