> 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.
