---------------------------------------
Summary: Unhandled case in VectorAssembler#transform
Key: SPARK-11902
URL: https://issues.apache.org/jira/browse/SPARK-11902
Project: Spark
Issue Type: Bug
Components: ML
Affects Versions: 1.5.2
Reporter: Benjamin Fradet
Priority: Minor
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
