Xusen Yin commented on SPARK-14381:
-----------------------------------

Comparing mllib.feature with ml.feature, there are only two APIs missing for ml.

1. HashingTF should have setAlgorithm. However, it is intended to do so 
according to JIRA: https://issues.apache.org/jira/browse/SPARK-14899

2. Word2vec should have maxSentenceLength. I created a new JIRA: 
https://issues.apache.org/jira/browse/SPARK-15793

> Review spark.ml parity for feature transformers

> Review parity of spark.ml vs. spark.mllib to ensure spark.ml contains all 
> functionality. List all missing items.
> This only covers Scala since we can compare Scala vs. Python in spark.ml 
> itself.
