If you have workflow engine around your job, that can take care of restarti=
ng the jobs. For direct hadoop execution,  please refer MAPREDUCE-227/ MAPR=
EDUCE-828

Not sure if it would work, you might try (effectively) blocking this job ru=
n by -set-priority on this job to very low and have other VHP jobs running.=
. Thanks!

Hi, all

I'm running a job on a 10-nodes cluster.
Now I want to add another node.
I have to reconfigure the dfs, and restart it, but I don't want to
stop the running job. It run for 1 week already.
What should I do? Is there a way to pause a job, and resume it after
dfs restart.

Thanks!
Xiao
