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.
