> Key: SPARK-10750
> URL: https://issues.apache.org/jira/browse/SPARK-10750
> Project: Spark
> Issue Type: Bug
> Components: ML
> Reporter: Yanbo Liang
> Priority: Minor
>
> Currently when you set illegal value for params of array type (such as IntArrayParam, DoubleArrayParam, StringArrayParam), it will throw IllegalArgumentException but with incomprehensible error information.
> For example:
> val vectorSlicer = new VectorSlicer().setInputCol("features").setOutputCol("result")
> vectorSlicer.setIndices(Array.empty).setNames(Array("f1", "f4", "f1"))
> It will throw IllegalArgumentException as:
> vectorSlicer_b3b4d1a10f43 parameter names given invalid value [Ljava.lang.String;@798256c5.
> java.lang.IllegalArgumentException: vectorSlicer_b3b4d1a10f43 parameter names given invalid value [Ljava.lang.String;@798256c5.
> Users can not understand which params were set incorrectly.
