-----------------------------------

             Summary: Expose RpcScheduling implementations as Public Interfaces
                 Key: HBASE-11497
                 URL: https://issues.apache.org/jira/browse/HBASE-11497
             Project: HBase
          Issue Type: Improvement
          Components: io, regionserver, Usability
    Affects Versions: 0.99.0, 0.98.4
            Reporter: Jesse Yates


In Phoenix-938 we are attempting to resolve cross-RS deadlocks in indexing by adding custom RPC handlers (so regular puts/reads don't interfere with index updates). However, we've run into a couple of snags where the interfaces change, making it a bit more difficult to support interoperability between minor versions as the underlying RPC handling changed (for the better, but still different :).

This would just mark those interfaces Public, Evolving, so we still have some flexibility, but don't break existing usage.

Note, this kind of thing will come up for any client who is doing custom RPC handling - beyond the recently added flexibility - but wants to stay in line with the current HBase implementation (rather than building their own RPC handling mechanisms).
