-------------------------------------
Summary: Support a function get DataFrame/DataSet from Transformer
Key: SPARK-20610
URL: https://issues.apache.org/jira/browse/SPARK-20610
Project: Spark
Issue Type: New Feature
Components: ML
Affects Versions: 2.1.0, 2.0.2
Reporter: darion yaphet
We are using stages to build our machine learning pipeline. Transformer will
transformers input dataset into another output dataset as our dataframe.
Sometime we will test the dataframe's result when developing the pipeline. But
it is looks like difficulty to running a test . If spark ml Stages could
support a interface to explore the dataframe processed by the stage , we could
use it to running test .
