                 URL: https://issues.apache.org/jira/browse/SPARK-6424

          Issue Type: Improvement
          Components: SQL

Currently, only user-defined generators (UDTF in Hive) are supported in native SparkSQL.
This enables third-parties to easily implement various operations on DataFrame.
