Weiwei Yang updated YARN-8195:
------------------------------
Priority: Critical (was: Major)
> Multiple target allocation tags in placement constraint is not working as
> expected
> ----------------------------------------------------------------------------------
>
> Key: YARN-8195
> URL: https://issues.apache.org/jira/browse/YARN-8195
> Project: Hadoop YARN
> Issue Type: Bug
> Reporter: Weiwei Yang
> Assignee: Weiwei Yang
> Priority: Critical
>
> While testing PC with multiple allocation tags, I found the behavior is not
> working as expected. To demonstrate this issue, imagine we have following PC
> {code}
> X=1, notin,node, A, B
> {code}
> this is to ask for a placement on a node that has no A or B.
> now assume we have A, B tags on a node with following numbers of allocations,
> {code}
> A(0), B(1)
> {code}
> expectation, as B has 1 allocation on this node, this node should not satisfy
> the PC. However in actual, it passes the check.
