Suresh Srinivas commented on HDFS-2843:
---------------------------------------
bq. Isn't this considered incompatible change?
This is a compatible change. On the wire uses label 3 to identify the field.
Depending on what a client was compiled with, in higher level language stubs,
say java, the name is either StorageInfoProto or NodeInfoProto.
> Rename protobuf message StorageInfoProto to NodeInfoProto

> StorageInfoProto has cTime, layoutVersion, namespaceID and clusterID. This is
> really information of a node that is part of the cluster, such as Namenode,
> Standby/Secondary/Backup/Checkpointer and datanodes. To reflect this, I want
> to rename it as NodeInfoProto from StorageInfoProto.
