Sean Owen created SPARK-27274:
---------------------------------
Summary: Refer to Scala 2.12 in docs; deprecate Scala 2.11 support
in 2.4.x
Key: SPARK-27274
URL: https://issues.apache.org/jira/browse/SPARK-27274
Project: Spark
Issue Type: Task
Components: Documentation, Spark Core
Affects Versions: 2.4.0
Reporter: Sean Owen
Assignee: Sean Owen
Scala 2.11 support is removed in Spark 3.0, so we should at least call it
deprecated in 2.4.x.
The 2.4.x docs current refer to Scala 2.11 artifacts. As 2.12 has been
supported since 2.4.0 without any significant issues, we should refer to 2.12
artifacts in the docs by default as well.
You could say this implicitly declares it 'unexperimental', if it ever was
deemed experimental, as we'd certainly support 2.12 and not change that support
for the foreseeable future.
