> Deprecate register* for UDFs in SQLContext and Catalog in PySpark
> -----------------------------------------------------------------
>
> Key: SPARK-23122
> URL: https://issues.apache.org/jira/browse/SPARK-23122
> Project: Spark
> Issue Type: Improvement
> Components: PySpark, SQL
> Affects Versions: 2.3.0
> Reporter: Hyukjin Kwon
> Priority: Major
>
> Seems we allow many other ways to register UDFs in SQL statements. Some are in {{SQLContext}} and some are in {{Catalog}}.
> These are also inconsistent with Java / Scala APIs. Seems we better deprecating them and put the logics into {{UDFRegistration}} ({{spark.udf.register*}}).
> Please see this discussion too - [https://github.com/apache/spark/pull/20217#issuecomment-357134926].
