As I said in the previous PRs (https://github.com/apache/spark/pull/30940#issuecomment-751583360, https://github.com/apache/spark/pull/30939#issuecomment-751544146), the Scala version of Kafak must be matched with Spark. Otherwise, there will be `[info] java.lang.NoClassDefFoundError: scala/math/Ordering$$anon$7` error. Kafka 2.7.0 uses Scala 2.12.2. So, in order to upgrade to Scala 2.12.13, we need a Kafka version which uses Scala 2.12.13 too. Otherwise, we cannot upgrade to Scala 2.12.13 in Spark side. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
