Jonathan Gray commented on HBASE-3141:
--------------------------------------
@Stack, this change isn't in constructor. the ordering change is within
finishInitialization() which is called in the run() of HMaster. We're already
handling exceptions/stopping appropriately at this stage.
> 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.
