Hey guys,

I was able to get YARN up and running using CGroups yesterday, but I'm not 
seeing YARN write to cpu.shares. As a result, the CPU-level isolation is just 
limited to equal-sharing between all NM processes. That is, if one proc asks 
for 10 virtual cores, and the other asks for 2, on a 12 vcore machine, they 
will still split 50/50, since their cpu.shares have 1024 for each.

Did I miss a configuration, or is cpu.shares currently not supported? Is it in 
the works?

Thanks!
Chris
