> --------------------------------------
>
> Key: SPARK-6734
> URL: https://issues.apache.org/jira/browse/SPARK-6734
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Reporter: Cheng Hao
>
> Some third-party UDTF extension, will generate more rows in the
> "GenericUDTF.close()" method, which is supported by Hive.
> https://cwiki.apache.org/confluence/display/Hive/DeveloperGuide+UDTF
> However, Spark SQL ignores the "GenericUDTF.close()", and it causes bug while
> porting job from Hive to Spark SQL.
