Junping Du commented on YARN-3304:

I would even think return -1 make more sense for unavailable case as it won't 
duplicate with zero resource consumption case. 

> Default return values for resources in ResourceCalculatorProcessTree are

> Per discussions in YARN-3296, getCpuUsagePercent() will return -1 for 
> unavailable case while other resource metrics are return 0 in the same case 
> which sounds inconsistent.
