As a user of HDFS, I want this one error message to be more useful.
-------------------------------------------------------------------

                 Key: HDFS-1954
                 URL: https://issues.apache.org/jira/browse/HDFS-1954
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: philo vivero


On NameNode web interface, you may get this warning:

  WARNING : There are about 32 missing blocks. Please check the log or run fsck.

If the cluster was started less than 14 days before, it would be great to add: "Is dfs.data.dir
defined?"

If at the point of that error message, that parameter could be checked, and error made "OMG
dfs.data.dir isn't defined!" that'd be even better. As is, troubleshooting undefined parameters
is a difficult proposition.

I suspect this is an easy fix.
