Description

JournalProtocol.proto uses NamenodeRegistration in methods such as journal() for identifying the source. I want to make it generic so that the method can be called with journal information to identify the journal. I plan to use the protocol also for sync purposes, where the source of the journal can be some thing other than namenode.
