[jira] [Created] (TEZ-1611) Change DataSource/Sink to be able to supply URIs for credentials

Bikas Saha created TEZ-1611:
-------------------------------

             Summary: Change DataSource/Sink to be able to supply URIs for credentials
                 Key: TEZ-1611
                 URL: https://issues.apache.org/jira/browse/TEZ-1611
             Project: Apache Tez
          Issue Type: Bug
            Reporter: Bikas Saha
            Assignee: Bikas Saha


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
