Yanbo Liang 7104ee0e5d [SPARK-10750] [ML] ML Param validate should print better error information ... 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. Take ```VectorSlicer.setNames``` as an example: ```scala val vectorSlicer = new VectorSlicer().setInputCol("features").setOutputCol("result") // The value of setNames must be contain distinct elements, so the next line will throw exception. 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. ``` We should distinguish the value of array type from primitive type at Param.validate(value: T), and we will get better error information. ``` vectorSlicer_3b744ea277b2 parameter names given invalid value [f1,f4,f1]. java.lang.IllegalArgumentException: vectorSlicer_3b744ea277b2 parameter names given invalid value [f1,f4,f1]. ``` Author: Yanbo Liang <ybliang8@gmail.com> Closes #8863 from yanboliang/spark-10750.		2015-09-22 11:00:33 -07:00
