Andy Isaacson updated HDFS-3612:
--------------------------------
Attachment: hdfs3612-2.txt
bq. double space after period
I always type double space after period, but I agree it's irrelevant. Fixed.
bq. role string
Agreed, nice improvement.
Attaching new patch.
> Single namenode image directory config warning can be improved

> Key: HDFS-3612

> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: name-node
> Affects Versions: 2.0.0-alpha
> Reporter: Harsh J
> Assignee: Andy Isaacson

> 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.
