> 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.
