> 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:
> {code}
