Description

Steps to reproduce:

Configure below property in resource-types.xml

<property>
 <name>yarn.resource-types</name>
 <value>yarn.io/gpu</value>
 </property>

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

if (!calc.isInvalidDivisor(cluster)) {
        float queueCapacityPerc = queue.getQueueInfo(false, false)
            .getCapacity();
        queueUsagePerc = calc.divide(cluster, usedResourceClone,
            Resources.multiply(cluster, queueCapacityPerc)) * 100;
        if (Float.isNaN(queueUsagePerc) || Float.isInfinite(queueUsagePerc)) {
          queueUsagePerc = 0.0f;
        }
        clusterUsagePerc =
            calc.divide(cluster, usedResourceClone, cluster) * 100;
      }

calc.isInvalidDivisor(cluster) always returns true as gpu resource is 0
