[jira] [Created] (SPARK-32787) requirement failed: The columns of A don't match the number of elements of x. A: 14, x: 10

mzz created SPARK-32787:
---------------------------

             Summary: requirement failed: The columns of A don't match the number of elements of x. A: 14, x: 10
                 Key: SPARK-32787
                 URL: https://issues.apache.org/jira/browse/SPARK-32787
             Project: Spark
          Issue Type: Bug
          Components: ML
    Affects Versions: 2.4.0
         Environment: Mac OS 
spark2.4.0
            Reporter: mzz


i use sparkML to train a gender model, but always report the following error when verifying the test data.When i use *FeatureHasher* ,the procedure is normal,but when i use one-hot,it  
will report a error:"requirement failed: The columns of A don't match the number of elements of x. A: 14, x: 10"
my key code:

{code:java}

   // hash feature
    //    val hasher = new FeatureHasher()
    //      .setInputCols("nickname_index", "title_index")
    //      .setOutputCol("feature")
    //    println("特征Hasher编码:")
    //    val tranning = hasher.transform(train_index)
    //    tranning.show(10)
    //    val testing = hasher.transform(test_index)

    // one-hot
    val encoder = new OneHotEncoderEstimator()
      .setInputCols(Array("nickname_index", "title_index"))
      .setOutputCols(Array("nickname_indexs", "title_indexs"))
    val tranning = encoder.fit(train_index).transform(train_index)
    val testing = encoder.fit(test_index).transform(test_index)

// my LR model
val lr = new LogisticRegression()
      .setMaxIter(10000)
      .setRegParam(0.01)
      .setElasticNetParam(0) // 0:L2, 1:L1
      .setFeaturesCol("nickname_indexs")
      .setFeaturesCol("title_indexs")
      .setLabelCol("label")
      .setPredictionCol("sex_predict") //预测列
    val model_lr = lr.fit(tranning)
    //    println(s"每个特征对应系数: ${model_lr.coefficients} 截距: ${model_lr.intercept}")
    //TODO.. 测试数据验证
    val predictions = model_lr.transform(testing)
    predictions.select("label", "sex_predict", "probability").show(100, false)
{code}

error:
