Haohui Mai commented on HDFS-5916:
----------------------------------
I have a few questions:
# What would be the semantic of the call if one of the deletion has failed?
# Should this operation be atomic?
# When should the changes propagate to other users?
# When should happen when the operation happen in the middle of NN failover?
I can't think of good answers of any of these questions, thus it looks to me
that the semantic at the file system layer is unclear.
Maybe it is better to implement as multiple RPC calls, but the RPC the messages
are sent in the same packet. Alternatively, if you are able to put the files
into a single directory then it might solve your problem :-)

> It would be nice to have an API to delete directories and files in bulk - for
> example, when deleting Hive partitions or HBase regions in large numbers, the
> code could avoid many trips to NN.
