Navis commented on HIVE-6809:
-----------------------------
Because it's way simpler. DropPartitionsRequest/Result felt too complicated for
me to do simple things like issue.
For the direct thirft users, I should suggest that use "bool
drop_partition_by_name()" instead of "bool drop_partition()". For users of
IMetaStoreClient, nothing changes.
> Support bulk deleting directories for partition drop with partial spec

> In busy hadoop system, dropping many of partitions takes much more time than
> expected. In hive-0.11.0, removing 1700 partitions by single partial spec
> took 90 minutes, which is reduced to 3 minutes when deleteData is set false.
> I couldn't test this in recent hive, which has HIVE-6256 but if the
> time-taking part is mostly from removing directories, it seemed not helpful
> to reduce whole processing time.
