> 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.
