Karthik Kambatla updated YARN-4885:
-----------------------------------
Attachment: yarn-4885-1.patch
Simple patch that just skips monitoring usage for a container if CPU usage is
negative, as this likely means container just started.
> Aggregate container utilization can be negative

> CPU usage information.
