------------------------------------
Summary: ml.feature should support default value of input column
Key: SPARK-15614
URL: https://issues.apache.org/jira/browse/SPARK-15614
Project: Spark
Issue Type: Brainstorming
Components: ML
Reporter: zhengruifeng
{{ml.clasification}} and {{ml.clustering}} use {{"features"}} as default input
column. While {{ml.feature}} use {{setInputCol}} method to set input column and
don't have default value, which is somewhat strange.
It may be nice to support default input column "features" in {{ml.feature}},
and we can make these implements extends {{HasFeaturesCol}} and make existing
{{setInputCol}} method just a alias.
I can work on this if needed.
