Aseem Bansal created SPARK-21481:
------------------------------------

             Summary: Add indexOf method in ml.feature.HashingTF similar to mllib.feature.HashingTF
                 Key: SPARK-21481
                 URL: https://issues.apache.org/jira/browse/SPARK-21481
             Project: Spark
          Issue Type: Improvement
          Components: ML
    Affects Versions: 2.2.0, 2.1.0
            Reporter: Aseem Bansal


If we want to find the index of any input based on hashing trick then it is possible in https://spark.apache.org/docs/2.2.0/api/scala/index.html#org.apache.spark.mllib.feature.HashingTF but not in https://spark.apache.org/docs/2.2.0/api/scala/index.html#org.apache.spark.ml.feature.HashingTF.

Should allow that for feature parity
