title: Spark ML - MulticlassClassificationEvaluator - can we get precision/recall by each class label?
body: <p>I am doing a multiclass prediction with random forest in Spark ML.</p>
  
  <p>For this MulticlassClassificationEvaluator() in spark ML, is it possible to get precision/recall by each class labels?</p>
  
  <p>Currently, I am only seeing precision/recall combined for all class together.</p>
