> Key: YARN-8804
> URL: https://issues.apache.org/jira/browse/YARN-8804
> Project: Hadoop YARN
> Issue Type: Bug
> Components: capacityscheduler
> Affects Versions: 3.2.0
> Reporter: Tao Yang
> Assignee: Tao Yang
> Priority: Critical
> Attachments: YARN-8804.001.patch, YARN-8804.002.patch,
> YARN-8804.003.patch
>
>
> This problem is due to YARN-4280, parent queue will deduct child queue's
> headroom when the child queue reached its resource limit and the skipped type
> is QUEUE_LIMIT, the resource limits of deepest parent queue will be correctly
> calculated, but for non-deepest parent queue, its headroom may be much more
> than the sum of reached-limit child queues' headroom, so that the resource
> limit of non-deepest parent may be much less than its true value and block
> the allocation for later queues.
> To reproduce this problem with UT:
> (1) Cluster has two nodes whose node resource both are <10GB, 10core> and
> 3-level queues as below, among them max-capacity of "c1" is 10 and others are
> all 100, so that max-capacity of queue "c1" is <2GB, 2core>
> {noformat}
> Root
> / | \
> a b c
> 10 20 70
> | \
> c1 c2
> 10(max=10) 90
> {noformat}
> (2) Submit app1 to queue "c1" and launch am1(resource=<1GB, 1 core>) on nm1
> (3) Submit app2 to queue "b" and launch am2(resource=<1GB, 1 core>) on nm1
> (4) app1 and app2 both ask one <2GB, 1core> containers.
> (5) nm1 do 1 heartbeat
> Now queue "c" has lower capacity percentage than queue "b", the allocation
> sequence will be "a" -> "c" -> "b",
> queue "c1" has reached queue limit so that requests of app1 should be
> pending,
> headroom of queue "c1" is <1GB, 1core> (=max-capacity - used),
> headroom of queue "c" is <18GB, 18core> (=max-capacity - used),
> after allocation for queue "c", resource limit of queue "b" will be wrongly
> calculated as <2GB, 2core>,
> headroom of queue "b" will be <1GB, 1core> (=resource-limit - used)
> so that scheduler won't allocate one container for app2 on nm1
