------------------------------
Summary: FairScheduler could not support DRF policy in lead queue
when parent queue is fair policy
Key: YARN-4378
URL: https://issues.apache.org/jira/browse/YARN-4378
Project: Hadoop YARN
Issue Type: Bug
Components: fairscheduler
Affects Versions: 2.5.2
Reporter: lachisis
If I configure fair-scheduler.xml as following, then the application submitted
to queue root.queueA.queueA1 will keep on Accepted status. And the resource
requirement of it's task will not be satisfied, because the queue
root.queueA.queueA1 have zero cpu.
<allocations>
<queue name="root">
<queue name="queueA">
<schedulingPolicy>fair</schedulingPolicy>
<queue name="queueA1">
<schedulingPolicy>drf</schedulingPolicy>
</queue>
</queue>
</queue>
<queuePlacementPolicy>
<policy create="false" name="specified" />
<policy create="false" name="user" />
<policy create="false" name="primaryGroup" />
<policy name="reject" />
</queuePlacementPolicy>
</allocations>
