Subject [jira] [Created] (HDFS-2060) DFS client RPCs using protobufs
Date Fri, 10 Jun 2011 17:39:59 GMT
DFS client RPCs using protobufs
-------------------------------

                 Key: HDFS-2060
                 URL: https://issues.apache.org/jira/browse/HDFS-2060
             Project: Hadoop HDFS
          Issue Type: New Feature
    Affects Versions: 0.23.0
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon


The most important place for wire-compatibility in DFS is between clients and the cluster,
since lockstep upgrade is very difficult and a single client may want to talk to multiple
server versions. So, I'd like to focus this JIRA on making the RPCs between the DFS client
and the NN/DNs wire-compatible using protocol buffer based serialization.
