Yang Wang commented on YARN-6578:
---------------------------------
[~cheersyang], thanks for your comment.
Have fixed the findbugs issues.
The failed UT seem to be another issue,
[YARN-8244|https://issues.apache.org/jira/browse/YARN-8244].
Do not need to fix checkstyle issues. Just as other metric variables, the
vMemMBsStat and vMemMBQuantiles could be public in ContainerMetrics.java.
> Return container resource utilization from NM ContainerStatus call

> When the applicationMaster wants to change(increase/decrease) resources of an
> allocated container, resource utilization is an important reference indicator
> for decision making. So, when AM call NMClient.getContainerStatus, resource
> utilization needs to be returned.
> Also container resource utilization need to report to RM to make better
> scheduling.
> So put resource utilization in ContainerStatus.
