---------------------------------------------------------
[~sravya],is there a particular reason we bother to implement getUser() as
opposed to relying on DefaultAuthorizationProvider's implementation? It's
hardly a security hole if the creator or the directory/file has access to it's
own files. Instead we should limit the plugin's scope to ACL features instead
of manipulating ownership bits.
I suggest we passthrough all requests to getUser() to the
DefaultAuthorizationProvider rather than having a plugin specific
implementation. In the event HDFS falls out of sync with Sentry we can just
remove the ACLs, leaving ownership in tact. Let me know your thoughts, I would
be more than happy to write/test this patch.
