             Summary: Inconsistency returning value of ML python models' properties
                 Key: SPARK-12780
                 URL: https://issues.apache.org/jira/browse/SPARK-12780
             Project: Spark
          Issue Type: Bug
          Components: ML, PySpark
            Reporter: Xusen Yin
            Priority: Minor


In spark/python/pyspark/ml/feature.py, StringIndexerModel has a property method named labels, which is different with other properties in other models.

In StringIndexerModel:
<code>
@property
    @since("1.5.0")
    def labels(self):
        """
        Ordered list of labels, corresponding to indices to be assigned.
        """
        return self._java_obj.labels
</code>

In CounterVectorizerModel (as an example):
<code>
@property
    @since("1.6.0")
    def vocabulary(self):
        """
        An array of terms in the vocabulary.
        """
        return self._call_java("vocabulary")
</code>

In StringIndexerModel, the returned value of labels is not an array of labels as expected. Otherwise it is a JavaMember of py4j.
