Benoy Antony commented on HADOOP-8726:
--------------------------------------
Another approach will be to delegate token and secret management to Credentials
itself and keep the entire Credentials object in Subject as PrivateCredentials.
This will avoid UGI class from handling the internals of Credentials. Any
drawbacks ?
> The Secrets in Credentials are not available to MR tasks
