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

             Summary: Remove unnecessary boxings and unboxings from PlacementConstraintParser.java
                 Key: YARN-7995
                 URL: https://issues.apache.org/jira/browse/YARN-7995
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Akira Ajisaka


{code}
      String maxCardinalityStr = resetElements.pop();
      Integer max = toInt(maxCardinalityStr);

      String minCardinalityStr = resetElements.pop();
      Integer min = toInt(minCardinalityStr);
{code}
{{toInt(String)}} does not return null, so {{Integer}} should be replaced with {{int}}.
