Thomas Graves commented on SPARK-17321:
---------------------------------------
Yes that sounds good. It wouldn't hurt to verify the second point. The NM
should throw an exception on container launch because it itself can't record
the container start thus can't recover.
> YARN shuffle service should use good disk from yarn.nodemanager.local-dirs

> Which caused by the first disk in yarn.nodemanager.local-dirs was broken.
> If we enabled spark.yarn.shuffle.stopOnFailure(SPARK-16505) we might lost
> hundred nodes which is unacceptable.
> We have 12 disks in yarn.nodemanager.local-dirs, so why not use other good
> disks if the first one is broken?
