             Summary: Make authentication Token retrieval amenable to coprocessor
                 Key: HBASE-17439
                 URL: https://issues.apache.org/jira/browse/HBASE-17439
             Project: HBase
          Issue Type: Improvement
            Reporter: Ted Yu


In the course of solving HBASE-17435, [~jerryhe] and I noticed that it is cumbersome for other coprocessor (such as SecureBulkLoadEndpoint) to retrieve authentication Token from region server.
Currently a Connection is needed to communicate with TokenProvider. Care is needed not to introduce dead lock on the server side.

This JIRA is to investigate feasibility of bypassing Connection / TokenProvider in the retrieval of authentication Token for custom coprocessor. This involves some refactoring around AuthenticationTokenSecretManager.
