> Key: YARN-8112
> URL: https://issues.apache.org/jira/browse/YARN-8112
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: resourcemanager
> Reporter: Weiwei Yang
> Priority: Major
>
> Currently following PC doesn't workÂ
> {code:java}
> -placement_spec zk=3,IN,NODE,zk
> -placement_spec zk=1,IN,NODE,zk
> {code}
> Expectation: place 3/1 zk containers in any node of the cluster.
> This is because when we do cardinality check, PC cannot be satisfied as there is no "zk" tag placed on any node. But this is a very common user-case, hence we need to support.
