> 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.
