philo vivero commented on HDFS-1954:
------------------------------------
Patrick, thanks for the advocacy and persistence. Todd, Suresh, et al, thanks
for trying to keep the quality high. And most of all, thanks everyone for
compromising on the "best we can do for now" instead of leaving it as was: I
think this will save many handfuls of hair from being pulled in the coming year
or two!

> 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.
