Subject [jira] [Comment Edited] (SPARK-3266) JavaDoubleRDD doesn't contain max()

----------------------------------------------------------

Broken for JavaDoubleRDD: fold, reduce, min, max
{code}
java.lang.NoSuchMethodError: org.apache.spark.api.java.JavaDoubleRDD.fold(Ljava/lang/Double;Lorg/apache/spark/api/java/function/Function2;)Ljava/lang/Double;
java.lang.NoSuchMethodError: org.apache.spark.api.java.JavaDoubleRDD.reduce(Lorg/apache/spark/api/java/function/Function2;)Ljava/lang/Double;
java.lang.NoSuchMethodError: org.apache.spark.api.java.JavaDoubleRDD.min(Ljava/util/Comparator;)Ljava/lang/Double;
java.lang.NoSuchMethodError: org.apache.spark.api.java.JavaDoubleRDD.max(Ljava/util/Comparator;)Ljava/lang/Double;
{code}

The "first" method would also be affected, but it seems that [~joshrosen] fixed that when
he first implemented JavaDoubleRDD.

Also, I would bet JavaPairRDD and JavaSchemaRDD have similar issues.

Also, I would bet JavaPairRDD.scala and JavaSchemaRDD.scala have similar issues.

> While I can compile my code, I see:
> Caused by: java.lang.NoSuchMethodError: org.apache.spark.api.java.JavaDoubleRDD.max(Ljava/util/Comparator;)Ljava/lang/Double;
> When I try to execute my Spark code. Stepping into the JavaDoubleRDD class, I don't notice
max()
> although it is clearly listed in the documentation.
