Hitesh Shah commented on YARN-3304:
-----------------------------------
[~kasha] 3.0.0 is a major release. I would assume all deprecated apis should be
removed. Given the length of time after which new major releases come into
existence, there would be no point of deprecating apis if they are not removed
in the next major release.
> ResourceCalculatorProcessTree#getCpuUsagePercent default return value is
> inconsistent with other getters

> 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.
