Subject [jira] [Created] (HDFS-2197) Refactor RPC call implementations out of NameNode class
Date Tue, 26 Jul 2011 01:45:09 GMT
Refactor RPC call implementations out of NameNode class

                 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

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.
