--------------------------------------------
@[~cnauroth]: Good to meet you, sir. I'd value your input on this change, given
that you've worked on the SBAP already.
bq. Great ideas in this patch!
Aww, shucks... You're only saying that because it's true. ;p
I should have a rebased version for you shortly. I'd better sort HIVE-9674 out
first.
> StorageBasedAuthProvider should batch namenode-calls where possible.

> 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.
