Reynold Xin created SPARK-13894:
-----------------------------------
Summary: SQLContext.range should return Dataset[Long]
Key: SPARK-13894
URL: https://issues.apache.org/jira/browse/SPARK-13894
Project: Spark
Issue Type: Sub-task
Components: SQL
Reporter: Reynold Xin
Rather than returning DataFrame, it should return a Dataset[Long]. The
documentation should still make it clear that the underlying schema consists of
a single long column named "value".
