There was a problem hiding this comment.
Seems OK to me. Nit: you can use s"... $otherType" interpolation.

There is an unhandled case in the transform method of VectorAssembler if one of the input columns doesn't have one of the supported type DoubleType, NumericType, BooleanType or VectorUDT. So, if you try to transform a column of StringType you get a cryptic "scala.MatchError: StringType". This PR aims to fix this, throwing a SparkException when dealing with an unknown column type. Author: BenFradet <benjamin.fradet@gmail.com> Closes #9885 from BenFradet/SPARK-11902. (cherry picked from commit 4be360d) Signed-off-by: Xiangrui Meng <meng@databricks.com>
