Description

Currently, the JournalManagers are instantiated before the NamespaceInfo is loaded from local storage directories. This is problematic since the JM may want to verify that the storage info associated with the journal matches the NN which is starting up (eg to prevent an operator accidentally configuring two clusters against the same remote journal storage). This JIRA rejiggers the initialization sequence so that the JMs receive NamespaceInfo as a constructor argument.
