    Description

      https://github.com/apache/spark/pull/14866
      and
      https://github.com/apache/spark/pull/15493
      added an explicit cross join to the dataset api in scala and python, requiring crossJoin to be used when there is no join condition.
      (JIRA: https://issues.apache.org/jira/browse/SPARK-17298)
      Add an explicit crossJoin to R as well so the API behavior is similar to Scala and python.
