> Key: YARN-4481
> URL: https://issues.apache.org/jira/browse/YARN-4481
> Project: Hadoop YARN
> Issue Type: Bug
> Components: capacity scheduler
> Affects Versions: 2.7.2
> Reporter: gu-chi
> Priority: Critical
> Attachments: jmx.txt
>
>
> Met a scenario of negative pending resource with capacity scheduler, in jmx, it shows:
> {noformat}
> "PendingMB" : -4096,
> "PendingVCores" : -1,
> "PendingContainers" : -1,
> {noformat}
> full jmx infomation attached.
> this is not just a jmx UI issue, the actual pending resource of queue is also negative as I see the debug log of
> bq. DEBUG | ResourceManager Event Processor | Skip this queue=root, because it doesn't need more resource, schedulingMode=RESPECT_PARTITION_EXCLUSIVITY node-partition= | ParentQueue.java
> this lead to the {{NULL_ASSIGNMENT}}
> The background is submitting hundreds of applications and consume all cluster resource and reservation happen. While running, network fault injected by some tool, injection types are delay,jitter
> ,repeat,packet loss and disorder. And then kill most of the applications submitted.
> Anyone also facing negative pending resource, or have idea of how this happen?
