Bikas Saha commented on TEZ-1611:
---------------------------------
Cant add unit test for this because UGI.isSecurityEnabled is a static method
that cannot be mocked and without it all token fetching is disabled.
[~rajesh.balamohan] Please review.
> Change DataSource/Sink to be able to supply URIs for credentials

> This way commonly used credentials (HDFS) can be obtained globally for the
> DAG and take advantage of previously cached credentials where appropriate.
> This would reduce round trips to the NN. The existing method to get
> credentials will still be in place for other credentials that we cannot
> obtain automatically via URIs
