Hyukjin Kwon resolved SPARK-12886.
----------------------------------
Resolution: Incomplete
> Expose params to control how feature names are generated
> --------------------------------------------------------
>
> Key: SPARK-12886
> URL: https://issues.apache.org/jira/browse/SPARK-12886
> Project: Spark
> Issue Type: New Feature
> Components: ML
> Reporter: Xiangrui Meng
> Priority: Major
> Labels: bulk-closed
>
> Feature names are generated during feature transformations. This would cause
> performance issues if there are a huge number of features. Sometimes, it is
> not useful to have feature names if the features are not to be examined
> manually. It would be nice to expose params to control feature name
> generation. This could be part of attribute API improvement.
