Cheng Lian resolved SPARK-4811.
-------------------------------
Resolution: Duplicate
Although this ticket was opened earlier, I mark this a duplicate of SPARK-6708
because SPARK-6708 gives clear reproduction steps.
> Custom UDTFs not working in Spark SQL
> -------------------------------------
>
> Key: SPARK-4811
> URL: https://issues.apache.org/jira/browse/SPARK-4811
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.1.0, 1.1.1, 1.2.1, 1.3.0
> Reporter: Saurabh Santhosh
> Priority: Critical
>
> I am using the Thrift srever interface to Spark SQL and using beeline to
> connect to it.
> I tried Spark SQL versions 1.1.0 and 1.1.1 and both are throwing the
> following exception when using any custom UDTF.
> These are the steps i did :
> *Created a UDTF 'com.x.y.xxx'.*
> Registered the UDTF using following query :
> *create temporary function xxx as 'com.x.y.xxx'*
> The registration went through without any errors. But when i tried executing
> the UDTF i got the following error.
> *java.lang.ClassNotFoundException: xxx*
> Funny thing is that Its trying to load the function name instead of the
> funtion class. The exception is at *line no: 81 in hiveudfs.scala*
> I have been at it for quite a long time.
