fail and kill all tasks without killing job.

[jay vyas]

Hi guys : I want my tasks to end/fail, but I don't want to kill my 
entire hadoop job.

I have a hadoop job that runs 5 hadoop jobs in a row.
Im on the last of those sub-jobs, and want to fail all tasks so that the 
task tracker stops delegating them,
and the hadoop main job can naturally come to a close.
However, when I run "hadoop job kill-attempt / fail-attempt ....", the 
jobtracker seems to simply relaunch
the same tasks with new ids.

How can I tell the jobtracker to give up on redelegating?
