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

             Summary: create java-friendly methods in RandomRDDs
                 Key: SPARK-3136
                 URL: https://issues.apache.org/jira/browse/SPARK-3136
             Project: Spark
          Issue Type: Improvement
          Components: MLlib
            Reporter: Xiangrui Meng
            Assignee: Xiangrui Meng


Though we don't use default argument for methods in RandomRDDs, it is still not easy for Java users to use because the output type is either `RDD[Double]` or `RDD[Vector]`. Java users should expect `JavaDoubleRDD` and `JavaRDD[Vector]`, respectively. We should create dedicated methods for Java users, and allow default arguments in Scala methods in RandomRDDs, to make life easier for both Java and Scala users.
