> Project: Hadoop YARN
> Issue Type: Bug
> Components: capacityscheduler
> Affects Versions: 3.2.0, 3.1.2
> Reporter: Tao Yang
> Assignee: Tao Yang
> Priority: Major
> Fix For: 3.2.0, 3.1.2

> Recently we found a new error as follows:
> {noformat}
> ERROR org.apache.hadoop.yarn.server.resourcemanager.scheduler.common.fica.FiCaSchedulerApp: node to unreserve doesn't exist, nodeid: host1:45454
> {noformat}
> Reproduce this problem:
> (1) Create a reserve proposal for app1 on node1
> (2) node1 is successfully decommissioned and removed from node tracker
> (3) Try to commit this outdated reserve proposal, it will be accepted and applied.
> This error may be occurred after decommissioning some NMs. The application who print the error log will always have a reserved container on non-exist (decommissioned) NM and the pending request will never be satisfied.
> To solve this problem, scheduler should check node state in FiCaSchedulerApp#accept to avoid committing outdated proposals on unusable nodes.
