-----------------------------------------
Summary: Transformer for splitting a Vector/Array column into
individual columns
Key: SPARK-14207
URL: https://issues.apache.org/jira/browse/SPARK-14207
Project: Spark
Issue Type: New Feature
Components: ML
Reporter: Joseph K. Bradley
Priority: Minor
Use case: Given feature vector column of type {{Vector}} or {{Array[Double]}},
split it into one column per feature. Each column should be labeled with the
original feature name if that is available from the metadata.
What shall we call this Transformer? Maybe VectorSplitter or VectorToColumns?
