[jira] [Commented] (SPARK-5117) Hive Generic UDFs don't cast correctly

["Michael Armbrust (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-5117?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14268049#comment-14268049 ] 

Michael Armbrust commented on SPARK-5117:
-----------------------------------------

Oh, okay.  Thanks for investigating!

Its annoying that hive makes breaking changes like this.  We should probably consider writing our own UDF replacements once the UDF framework is cleaned up.

> Here's a test cast that is failing in master:
> {code}
>   createQueryTest("generic udf casting",
>     """SELECT LPAD("test",5, 0) FROM src LIMIT 1""")
> {code}
> This appears to be a regression from Spark 1.1
