Jonathan Gray updated HBASE-3141:
---------------------------------

    Attachment: HBASE-3141-v1.patch

Patch moves start of service threads to before we put up cluster up flag.  This 
kind of deals with this issue.

I think real fix is for RPC server to properly handle/reject any requests when 
it's in a weird state between construction and starting.

> Master RPC server needs to be started before an RS can check in

> Starting up an RPC server is done in two steps.  In the constructor, we 
> instantiate the RPC server.  Then in startServiceThreads() we start() it.
> If someone RPCs in between the instantiation and the start(), it seems that 
> bad things can happen.  We need to make sure this can't happen and there 
> aren't any races here.
