Subject [jira] [Commented] (YARN-7116) CapacityScheduler Web UI: Queue's AM usage is always show on per-user's AM usage.
Date Tue, 29 Aug 2017 11:20:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-7116?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16145128#comment-16145128

Sunil G commented on YARN-7116:
-------------------------------

[~bibinchundatt], I didnt understand your point clearly. As per below code, we consider all
resource usages per label and updating same. Below code is from trunk. Post this patch, we
handle {{amUsed}} more cleanly. Please update me if I understood your comment wrongly.

{code}
        PartitionResourcesInfo resourceUsages = lqinfo
            .getResources()
            .getPartitionResourceUsageInfo((nodeLabel == null) ? "" : nodeLabel);
        if (nodeLabel != null) {
          resourcesUsed = userInfo.getResourceUsageInfo()
              .getPartitionResourceUsageInfo(nodeLabel).getUsed();
        }
        ResourceInfo amUsed = (resourceUsages.getAmUsed() == null)
            ? new ResourceInfo(Resources.none())
            : resourceUsages.getAmUsed();
{code}

> On CapacityScheduler's web UI, AM usage of different users belong to the same queue always
shows queue's AM usage. 
> The root cause is: under CapacitySchedulerPage.

>         tbody.tr().td(userInfo.getUsername())
>             .td(userInfo.getUserResourceLimit().toString())
>             .td(resourcesUsed.toString())
>             .td(resourceUsages.getAMLimit().toString())
>             .td(amUsed.toString())
>             .td(Integer.toString(userInfo.getNumActiveApplications()))
>             .td(Integer.toString(userInfo.getNumPendingApplications()))._();
> {code}
> Instead of amUsed.toString(), it should use userInfo.getAmUsed().
