Apache Spark reassigned SPARK-20729:
------------------------------------
Assignee: (was: Apache Spark)
> Reduce boilerplate in Spark ML models
> -------------------------------------
>
> Key: SPARK-20729
> URL: https://issues.apache.org/jira/browse/SPARK-20729
> Project: Spark
> Issue Type: Improvement
> Components: ML, SparkR
> Affects Versions: 2.2.0
> Reporter: Maciej Szymkiewicz
>
> Currently we implement both {{predict}} and {{write.ml}} for ML wrappers,
> although R code is virtually identical and all the model specific logic is
> handled by Scala wrappers.
> Since we use S4 classes we can extract these functionalities into separate
> traits.
