Jesse Yates commented on HBASE-11497:
-------------------------------------

For right now, I'm thinking we need to expose SimpleRpcScheduler as well as RpcExecutor and its subclasses.

> 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).
