> 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.
