The following test is not working:

FROM srcpart
INSERT OVERWRITE TABLE dest1 SELECT srcpart.key, srcpart.value, srcpart.hr, srcpart.ds WHERE
srcpart.key < 100 and srcpart.ds = '2008-04-08' and srcpart.hr = '12'
INSERT OVERWRITE TABLE dest2 SELECT srcpart.key, srcpart.value, srcpart.hr, srcpart.ds WHERE
srcpart.key < 100 and srcpart.ds = '2008-04-09' and srcpart.hr = '12';


if the partitions are different. It seems that all the partitions are pruned if they are different.
