Xiangrui Meng updated SPARK-16153:
----------------------------------
    Description: 
Env: Scala 2.11.8, Java 1.7.0_79

We recently deprecated setLabelCol in ChiSqSelectorModel:

{code}
  /** @group setParam */
  @Since("1.6.0")
  @deprecated("labelCol is not used by ChiSqSelectorModel.", "2.0.0")
  def setLabelCol(value: String): this.type = set(labelCol, value)
{code}

This unfortunately hit a genjavadoc bug and broken doc generation. This is the 
generated Java code:

{code}
  /** @group setParam */
  public  org.apache.spark.ml.feature.ChiSqSelectorModel setOutputCol 
(java.lang.String value)  { throw new RuntimeException(); }
   *
   * @deprecated labelCol is not used by ChiSqSelectorModel. Since 2.0.0.
  */
  public  org.apache.spark.ml.feature.ChiSqSelectorModel setLabelCol 
(java.lang.String value)  { throw new RuntimeException(); }
{code}

Switching to multiline is a workaround.
