Hi guys:  I'm getting an odd error  involving a file called "toBeDeleted".
I've never seen this - somehow its blocking my task trackers from starting.

2013-03-06 16:19:24,657 ERROR org.apache.hadoop.mapred.TaskTracker: Can not
start task tracker because java.lang.RuntimeException: Cannot find root
