Parameter 'yarn.nodemanager.resource.cpu-cores' does not work
Hi,

With Hadoop 2.0.4-alpha, yarn.nodemanager.resource.cpu-cores does not work
for me:
1. The performance of running same terasort job do not change, even after
increasing or decreasing the value of 'yarn.nodemanager.resource.cpu-cores'
in yarn-site.xml and restart the yarn cluster.

2. Even if I set the value of both
'yarn.nodemanager.resource.cpu-cores' and
'yarn.nodemanager.vcores-pcores-ratio' to 0, the MR job still could
complete without any exception, but the expected behavior should be that no
cpu could be assigned to the container, and then no job could be executed
on the cluster. Right?

Thanks!
