Patrick Hunt commented on HDFS-1954:
------------------------------------

Yea that's on me, sorry. It's weird -- the patch test indicated success. I'll update the patch,
incl the test, once Konstantin updates the FAQ. Thanks Suresh/Todd.

> 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.
