Gary Helmling created HBASE-15741:
-------------------------------------

             Summary: TokenProvider coprocessor RPC incompatibile between 1.2 and 1.3
                 Key: HBASE-15741
                 URL: https://issues.apache.org/jira/browse/HBASE-15741
             Project: HBase
          Issue Type: Bug
          Components: Coprocessors
    Affects Versions: 1.3.0
            Reporter: Gary Helmling
            Priority: Blocker


Attempting to run a map reduce job with a 1.3 client on a secure cluster running 1.2 is failing
when making the coprocessor rpc to obtain a delegation token:

This is talking to a 1.2 server.  Running with a 1.2 client works.  I believe this is due
to HBASE-14077, where we added package names to the protobuf files.

This is causing 1.2 and 1.3 to disagree on the name of the AuthenticationService:
* 1.2 = AuthenticationService
* 1.3 = hbase.pb.AuthenticationService

I think this is effectively a break in client-server wire compatibility between 1.2 and 1.3,
since this is calling a built-in coprocessor required for security.
