> 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.
