--------------------------------------

             Summary: Wrong error message in RM placement constraints check
                 Key: YARN-8681
                 URL: https://issues.apache.org/jira/browse/YARN-8681
             Project: Hadoop YARN
          Issue Type: Bug
          Components: scheduler
    Affects Versions: 3.1.1, 3.2.0
            Reporter: Daniel Templeton


In {{SingleConstraintAppPlacementAllocator.validateAndSetSchedulingRequest()}} I see the following:

{code}      if (singleConstraint.getMinCardinality() != 0
          || singleConstraint.getMaxCardinality() != 0) {
        throwExceptionWithMetaInfo(
            "Only support anti-affinity, which is: minCardinality=0, "
                + "maxCardinality=1");
      }{code}

I think the error message should say {{"maxCardinality=0"}}
