> For HA, the NameNode will gain a bit of a state machine, to be able to 
> transition between standby and active states. This would be cleaner in the 
> code if the {{NameNode}} class were just a container for various services, as 
> discussed in HDFS-1974. It's also nice for testing, where it would become 
> easier to construct just the RPC handlers around a mock NameSystem, with no 
> HTTP server, for example.
> This JIRA is to move all of the protocol implementations out of {{NameNode}} 
> into a separate {{NameNodeRPCServer}} class.
