> capacity scheduler doesn't set node label to reserved container
> ---------------------------------------------------------------
>
> Key: YARN-8743
> URL: https://issues.apache.org/jira/browse/YARN-8743
> Project: Hadoop YARN
> Issue Type: Bug
> Components: capacity scheduler, scheduler preemption
> Reporter: Hu Ziqian
> Assignee: Hu Ziqian
> Priority: Major
> Attachments: YARN-8743.001.patch, YARN-8743.002.patch

>
> capacity scheduler doesn't set node label when new a reserved container's
> RMContainerImpl. When allocate this container, leafQueue will treat it as a
> ignorePartitionExclusivityRMContainer.
> It will cause preempt failure. When preempt happens, the preemption policy
> will try to preempt the reserved container while leafQueue doesn't remove it
> from ignorePartitionExclusivityRMContainers. In our cluster, we found that
> preemption policy will always try to preempt the reserved container and
> actually preempt nothing.
> We set the node label information to reserved container's RMContainerImpl
> and redo our test. The preemption performs as expected.
