> 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,
> Resources.multiply(cluster, queueCapacityPerc)) * 100;
> 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
