---------------------------------
Summary: PySpark Pipeline and PipelineModel should take advantages
of its Scala companion
Key: SPARK-13388
URL: https://issues.apache.org/jira/browse/SPARK-13388
Project: Spark
Issue Type: Improvement
Components: PySpark
Reporter: Xusen Yin
Priority: Minor
Pipeline and PipelineModel in PySpark, unlike other estimators and models, are
implemented in Python side, which makes it difficult to reuse new methods like
save/load of their Scala companions and bring maintenance costs. To utilize
current and upcoming new features, we should refactor it similar with other
estimators/models in PySpark to call its Scala implementation.
