Brandon Li commented on HDFS-3229:
----------------------------------
Todd, thanks for the comments! getEditLogManifest() call (or a likely one)
could be used to list the finalized logs on a JournalNode.
To copy edit segments, we may need to something different here. The proposal is
to use the same Journal RPC server to download edit segments instead of
resorting HTTP. In that, the JournalNode doesn't have to start an additional
HTTP server which could cause some subtle issues and make debugging more
difficult.
> add JournalProtocol RPCs to list finalized edit segments, and read edit
> segment file from JournalNode.
