Description

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.
