Andy Isaacson commented on HDFS-3612:
-------------------------------------
Harsh - they're slightly different warnings, about name.dir and edits.dir
respectively. Since the user needs to take two different actions to fix the
problem, I think two warnings is reasonable.
As an admin, I'd be annoyed to get just the name.dir error, grumble, fix it,
restart, get the edits.dir error, gruble louder, fix it, restart ...
> Single namenode image directory config warning can be improved

> Key: HDFS-3612
> URL: https://issues.apache.org/jira/browse/HDFS-3612
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: name-node
> Affects Versions: 2.0.0-alpha
> Reporter: Harsh J
> Priority: Trivial
> Labels: newbie
>
> 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.
