----------------------------------------
Looks like we have a regression :
org.apache.hadoop.hive.ql.security.TestStorageBasedMetastoreAuthorizationDrops.testDropPartition
is failing while it shouldn't. This happened in the 9th May run as well.

[~mithun], if we can look at this and resolve this, we can get this into 1.2.1,
but if not, then I'm afraid this will have to be deferred out of branch-1.2,
and make it in 1.3/2.0 .
> 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.
