Zhenhao Li commented on FLINK-13414: ------------------------------------ I found another good reason to drop the user Scala API completely. It is impossible to use the test harness classes to test Scala UDFs. https://issues.apache.org/jira/browse/FLINK-22615 I agree with [~sjwiesman] that the way to go is to offload the burden of Scala support from the Flink community. As long as Flink doesn't leak its internal Scala dependencies, I think many Scala users, including me, will be happy to use the Java API. With Scala 3, I think there will be community libraries building higher abstractions over the Java API. > Add support for Scala 2.13 > -------------------------- > > Key: FLINK-13414 > URL: https://issues.apache.org/jira/browse/FLINK-13414 > Project: Flink > Issue Type: New Feature > Components: API / Scala > Reporter: Chaoran Yu > Priority: Major > -- This message was sent by Atlassian Jira (v8.3.4#803005)
