> Unhandled case in VectorAssembler#transform
> -------------------------------------------
>
> Key: SPARK-11902
> URL: https://issues.apache.org/jira/browse/SPARK-11902
> Project: Spark
> Issue Type: Improvement
> Components: ML
> Affects Versions: 1.5.2
> Reporter: Benjamin Fradet
> Assignee: Benjamin Fradet
> Priority: Trivial
> Fix For: 1.6.0
>
>
> I noticed that 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".
> Will submit a PR shortly
