superuser hadoop is not allowed to drop table because parent dir is not writable by superuser

[lalaguozhe]

Hive do client permission check when dropping a table. But super user didn't match all of the hdfs unix bits of the parent table dir.Therefore superuser can't drop table. It doesn't make sense. Superuser should bypass the authorization.

FAILED: Error in metadata: MetaException(message:Table metadata not deleted since hdfs://10.2.6.102/user/hive/warehouse/bi.db is not writable by hadoop@DIANPING.COM)
