Randall Whitman commented on SPARK-7768:
----------------------------------------
Am I missing something?
As far as I can see, the @Experimental annotation is still present on class
UserDefinedFunction -
https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/expressions/UserDefinedFunction.scala
Also, I have not seen any mention of having addressed the design issue of using
@SQLUserDefinedType with third-party libraries, that is discussed in this JIRA,
2015/05/21 through 2015/06/12.
