Bilwa S T created YARN-10588:
--------------------------------
Summary: Percentage of queue and cluster is zero in WebUI
Key: YARN-10588
URL: https://issues.apache.org/jira/browse/YARN-10588
Project: Hadoop YARN
Issue Type: Bug
Reporter: Bilwa S T
Assignee: Bilwa S T
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
