when I execute

cat /proc/cpuinfo | grep ^processor | wc = -l

I get 2, do I need to specify this = value in yarn.nodemanager.resource.cpu-vcores

or there is some kind of ratio between pcore and = vcore?

I found yarn.nodemanager.vcores-pcores-ratio = but it seems that is is deprecated, since I cannot find it in hadoop = 2.5.1.

Thank you.
