Hi, All. Apache Spark community starts to publish Scala 2.13 Maven artifacts daily.
https://repository.apache.org/content/repositories/snapshots/org/apache/spark/spark-core_2.13/3.2.0-SNAPSHOT/ It aims to encourage more tests on Scala 2.13 (and Scala 3) and to identify issues in advance for Apache Spark 3.2.0. In addition, recently we upgraded from Scala 2.12.10 to Scala 2.12.13 nine days ago but we decided to revert this today due to https://github.com/scala/bug/issues/12038 [SPARK-31168][SPARK-33913][BUILD] Upgrade Scala to 2.12.13 and Kafka to 2.7.0 https://github.com/apache/spark/commit/a65e86a65e39f3a61c3248b006e897effd7e4c2a Revert "[SPARK-31168][SPARK-33913][BUILD] Upgrade Scala to 2.12.13 and Kafka to 2.7.0" https://github.com/apache/spark/commit/1217c8b4181d8b8f54b7f0b0510d37ba773eeaa3 The scala bug is originally open for Scala 2.13, but we didn't downgrade the Scala 2.13 version because it's not officially supported yet. It's still using Scala 2.13.4. Please file a JIRA if you hit some issues with the Scala 2.13 Maven artifacts. Bests, Dongjoon.
