------------------------------
Assignee: Jeff Zhang
> Allow PySpark to register Java UDF
> ----------------------------------
>
> Key: SPARK-11775
> URL: https://issues.apache.org/jira/browse/SPARK-11775
> Project: Spark
> Issue Type: New Feature
> Components: PySpark, SQL
> Reporter: Jeff Zhang
> Assignee: Jeff Zhang
> Fix For: 2.1.0
>
>
> Currently pyspark can only call the builtin java UDF, but can not call custom java UDF. It would be better to allow that. 2 benefits:
> * Leverage the power of rich third party java library
> * Improve the performance. Because if we use python UDF, python daemons will be started on worker which will affect the performance.
