-----------------------------------------------------------------
Hi, just so this gets into the precommit queue, could you upload a
HIVE-9736.5.patch which is really the combination of HIVE-9681 and
HIVE-9736.4.patch and set this jira to patch-available?
When committing it, I'll be sure to use the .4.patch, even uploading a new
.6.patch which is its equivalent to make it clear for future jira visitors, but
this would make the precommit queue pick it up.

> Consider a table partitioned by 2 keys (dt, region). Say a dt partition could
> have 10000 associated regions. Consider that the user does:
> {code:sql}
> ALTER TABLE my_table DROP PARTITION (dt='20150101');
> {code}
> As things stand now, {{StorageBasedAuthProvider}} will make individual
> {{DistributedFileSystem.listStatus()}} calls for each partition-directory,
> and authorize each one separately. It'd be faster to batch the calls, and
> examine multiple FileStatus objects at once.
