[jira] [Updated] (YARN-4885) Aggregate container utilization can be negative

     [ https://issues.apache.org/jira/browse/YARN-4885?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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.

> While working on YARN-1011, I noticed the aggregate container utilization the NM reports to RM can be negative (CPU). This is likely because of UNAVAILABLE CPU usage information.
