paul sutter commented on HADOOP-27:
-----------------------------------


One impact of this fix is that an invalid directory name in the temp files list will \
now prevent a node from running, whereas before that was tolerated.

We have a couple of nodes in our cluster with 3 drives instead of 4 (they each have a \
dead drive), and previously we were able to run just fine with one config file on all \
nodes.
