Sergey Shelukhin commented on HIVE-6809:
----------------------------------------
On code level patch looks ok.
1) I am not sure how acceptable it is to break thrift APIs.
[~ashutoshc] can you comment?
I wonder again if you can augment existing dropPartitions req/resp based API?
Or if not, maybe convert existing ones to req/resp if they are changing anyway,
so it would be easier to change them later.
2) Can this also use bulk delete path from database?
> 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.
