Subject [GitHub] spark issue #15704: [SPARK-17732][SQL] ALTER TABLE DROP PARTITION should sup...

Github user gatorsmile commented on the issue:
    When the partition specs have `equal to` only, our implementation first checks all before
starting the actual drop. See the [codes](

    In addition, when we hit any failure after starting to drop the partitions, we log the
following error message:
         |Attempt to drop the partition specs in table '$table' database '$db':
         |In this attempt, the following partitions have been dropped successfully:
         |The remaining partitions have not been dropped:
    I think we should make the behaviors of DROP PARTITION consistent, no matter whether there
exists any non-equal-to comparator.
