    Description

      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.
