> Currently, the "namenode -format" and "namenode -initializeSharedEdits" 
> commands do not understand how to do anything with non-file-based shared 
> storage. This affects both BookKeeperJournalManager and QuorumJournalManager.
> This JIRA is to plumb through the formatting of edits directories using 
> pluggable journal manager implementations so that no separate step needs to 
> be taken to format them -- the same commands will work for NFS-based storage 
> or one of the alternate implementations.
