> StorageContainerLocationProtocol is an internal Java interface and is not the actual Hadoop RPC/Protobuf protocol. The wire protocol is defined by StorageContainerLocationProtocolService and exposed through StorageContainerLocationProtocolPB.
>  
> Both StorageContainerLocationProtocol and StorageContainerLocationProtocolPB declared RPC metadata. However, SCM RPC server registration, client proxies, translators, and failover providers use StorageContainerLocationProtocolPB. Therefore, the versionID and @KerberosInfo declared by StorageContainerLocationProtocol were redundant.
