> HADOOP-1170 removed the disk checking feature. But this is a needed feature
> for maintaining a large cluster. I agree that checking the disk on every I/O
> is too costly. A nicer approach is to have a thread that periodically do a
> disk check. It then automatically decommissions itself when any error occurs.
