Eric Lo updated SPARK-23453:
Description:
Here is a weird problem I just ran into... My scenario is that I need to
compile UDAF dynamically at runtime but it never worked.
I am using Scala 2.11.11 and Spark 2.2.1, please refer to my [StackOverflow
post|https://stackoverflow.com/questions/48820212/toolbox-compiled-spark-udaf-causes-java-lang-internalerror-malformed-class-name]
for detailed information and minimal examples. The problem itself is very
similar to other Malformed class name tickets (for example
-[https://github.com/apache/spark/pull/9568])- which were caused by calling
getSimpleName of nested class/object but actually it is different in this case
and the problem is still there. The getSimpleName issue has been fixed in Java
9 which Spark doesn't support it yet...so...any solution/workaround is
appreciated.
