> Key: HDFS-2197
> URL: https://issues.apache.org/jira/browse/HDFS-2197
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: name-node
> Affects Versions: 0.23.0
> Reporter: Todd Lipcon
> Assignee: Todd Lipcon
> Attachments: hdfs-2197-2.txt, hdfs-2197-3.txt, hdfs-2197-4.txt,

> 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.
