Richard Williamson commented on HIVE-1579:
------------------------------------------
I may have found root cause on this error - when increasing the memory for my
failed runs, I left off the dash as follows:
set mapred.child.java.opts=Xmx1100M;
When correcting with:
set mapred.child.java.opts=-Xmx1100M;
It ran without errors...
> showJobFailDebugInfo fails job if tasktracker does not respond
