             Summary: 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


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.
