Sanjay Radia commented on HDFS-892:
-----------------------------------
Doug, you defined:
+public interface NamenodeProtocols
+ extends ClientProtocol,
+ DatanodeProtocol,
+ NamenodeProtocol,
+ RefreshAuthorizationPolicyProtocol,
+ RefreshUserToGroupMappingsProtocol { ...}
Will this prevent us from putting the DatanodeProtocol in a different port?
Was the super-interface added to avoid the duplicate "versioned" interface?
> optionally use Avro for namenode RPC
