-----------------------------------------------------------
I have sent out an invite for Thursday (July 12) 10AM PST, let me know the
preferred time slot if this isn't a good time. Ping me if anyone wants to join
but didn't receive the meeting invite.
FWIW, the case we want to support here is the client should use the creation
ugi regardless of the context. The oozie ugi callstack is from a real cluster
usage out of oozie.

> While calling KeyProviderCryptoExtension decryptEncryptedKey the call stack
> might not have doAs privileged execution call (in the DFSClient for example).
> This results in loosing the proxy user from UGI as UGI.getCurrentUser finds
> no AccessControllerContext and does a re-login for the login user only.
> This can cause the following for example: if we have set up the oozie user to
> be entitled to perform actions on behalf of example_user but oozie is
> forbidden to decrypt any EDEK (for security reasons), due to the above issue,
> example_user entitlements are lost from UGI and the following error is
> reported:
