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