> Currently, if you configure the NameNode to run with just one
> dfs.namenode.name.dir directory, it prints:
> {code}
> 12/07/08 20:00:22 WARN namenode.FSNamesystem: Only one dfs.namenode.name.dir
> directory configured , beware data loss!{code}
> We can improve this in a few ways as it is slightly ambiguous:
> # Fix punctuation spacing, there's always a space after a punctuation mark
> but never before one.
> # Perhaps the message is better printed with a reason of why it may cause a
> scare of data loss. For instance, we can print "Detected a single storage
> directory in dfs.namenode.name.dir configuration. Beware of dataloss due to
> lack of redundant storage directories" or so.
