Thomas Graves commented on MAPREDUCE-2555:
------------------------------------------
I think all we want to do is get the child to exit and not generate all the log
messages. To do that we can have the TaskTracker::statusUpdate return false if
the validateJVM throws. The only catch to that is the
TaskTracker::commitPending call doesn't return boolean so will have to have it
still throw.
