[jira] [Commented] (YARN-10588) Percentage of queue and cluster is zero in WebUI

["Eric Payne (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/YARN-10588?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17293221#comment-17293221 ] 

Eric Payne commented on YARN-10588:
-----------------------------------

[~BilwaST], sorry for the delay in replying.

bq. Changing {{DominantResourceCalculator#isInvalidDivisor}} to {{DominantResourceCalculator#isAllInvalidDivisor}} would solve problem. What do you think?

I verified that {{isAllInvalidDivisor}} is only true if all resources are 0. So, I agree that you could just replace with that.

[~Jim_Brennan], do you agree?

> Steps to reproduce:
> Configure below property in resource-types.xml
> {code:java}
> <property>
>  <name>yarn.resource-types</name>
>  <value>yarn.io/gpu</value>
>  </property>{code}
> Submit a job
> In UI you can see % Of Queue and % Of Cluster is zero for the submitted application
>  
> This is because in SchedulerApplicationAttempt has below check for calculating queueUsagePerc and clusterUsagePerc
> {code:java}
> if (!calc.isInvalidDivisor(cluster)) {
>         float queueCapacityPerc = queue.getQueueInfo(false, false)
>             .getCapacity();
>         queueUsagePerc = calc.divide(cluster, usedResourceClone,

>         if (Float.isNaN(queueUsagePerc) || Float.isInfinite(queueUsagePerc)) {
>           queueUsagePerc = 0.0f;
>         }
>         clusterUsagePerc =
>             calc.divide(cluster, usedResourceClone, cluster) * 100;
>       }
> {code}
> calc.isInvalidDivisor(cluster) always returns true as gpu resource is 0
