> Key: SPARK-16153
> URL: https://issues.apache.org/jira/browse/SPARK-16153
> Project: Spark
> Issue Type: Bug
> Components: Documentation
> Affects Versions: 2.0.0
> Reporter: Xiangrui Meng
> Assignee: Xiangrui Meng
> Fix For: 2.0.0
>
>
> 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. Reported the bug to genjavadoc at https://github.com/typesafehub/genjavadoc/issues/85.
