[jira] [Created] (SPARK-14372) Dataset.randomSplit() needs a Java version

Cheng Lian created SPARK-14372:
----------------------------------

             Summary: Dataset.randomSplit() needs a Java version
                 Key: SPARK-14372
                 URL: https://issues.apache.org/jira/browse/SPARK-14372
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 2.0.0
            Reporter: Cheng Lian


{{Dataset.randomSplit()}} now returns {{Array\[Dataset\[T\]\]}}, which doesn't work for Java users since Java methods can't return generic arrays. We may want something like {{randomSplitAsList()}}.
