--------------------------------------------
Summary: [ML] PolynomialExpansion and Normalizer should validate
input type
Key: SPARK-13340
URL: https://issues.apache.org/jira/browse/SPARK-13340
Project: Spark
Issue Type: Bug
Components: ML, MLlib
Affects Versions: 1.6.0, 2.0.0
Reporter: Grzegorz Chilkiewicz
Priority: Trivial
PolynomialExpansion and Normalizer should override
UnaryTransformer::validateInputType
Now, in case of trying to operate on String column:
java.lang.ClassCastException: java.lang.String cannot be cast to
org.apache.spark.mllib.linalg.Vector
is thrown, but:
java.lang.IllegalArgumentException: requirement failed: Input type must be
VectorUDT but got StringType
will be more clear and adequate
