Ismael Juma commented on SPARK-25075:
-------------------------------------
Thanks Dongjoon, I totally agree that stable Scala 2.13 support needs to come
first.
I was asking because we are also trying to figure out the strategy for Kafka
when it comes to Scala versions support. We have supported Scala 2.13 for a
while, but Scala 2.12 is still widely used due to Spark.
I think I will propose to deprecate Scala 2.12 support in Apache Kafka 3.0,
which would roughly align with Spark 3.2. And removal would happen around 1
year after that.
