Eric Lo created SPARK-23453: ------------------------------- Summary: ToolBox compiled Spark UDAF causes java.lang.InternalError: Malformed class name Key: SPARK-23453 URL: https://issues.apache.org/jira/browse/SPARK-23453 Project: Spark Issue Type: Bug Components: Spark Core Affects Versions: 2.2.1 Environment: Spark 2.2.1 Scala 2.11.11 JDK 1.8 Reporter: Eric Lo
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. 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
