             Summary: restore inheritPerms functionality and extend it to ACID
                 Key: HIVE-18689
             Project: Hive
          Issue Type: Bug
            Reporter: Sergey Shelukhin
            Assignee: Sergey Shelukhin

This functionality was removed for no clear reason (if it doesn't apply to some 
use case it can just be disabled).
It's still in use; in fact, it should be extended to ACID table subdirectories.

This patch restores the functionality with some cleanup (to not access config 
everywhere, mostly), disables it by default, and extends it to ACID tables.

There's a coming HDFS feature that will automatically inherit permissions. When 
that is shipped in a non-beta version and stabilized a bit, we can remove this 
functionality... however I dunno if that is good for other potential use cases, 
like non-HDFS file systems that do have a concept of a directory (Isilon?)
