> To drop a partition from a Hive table, this works:
> ALTER TABLE foo DROP PARTITION(ds = 'date')
> ...but it should also work to drop all partitions prior to date.
> ALTER TABLE foo DROP PARTITION(ds < 'date')
> This task is to implement ALTER TABLE DROP PARTITION for all of the comparators, < > <= >= <> = != instead of just for =.
