-----------------------------------------
Summary: Spark - Scala 2.12 compatibility
Key: SPARK-27487
URL: https://issues.apache.org/jira/browse/SPARK-27487
Project: Spark
Issue Type: Bug
Components: Build, Deploy
Affects Versions: 2.4.1
Environment: Scala 2.12.7, Hadoop 2.7.7, Spark 2.4.1.
Reporter: Vadym Holubnychyi
Hi, I've faced one interesting problem during the development. It's written
that Spark 2.4.1 is compatible with Scala 2.12 (a minor version is not
specified!). So I tried to deploy an application that was written on Scala
2.12.7 and I got a lot of serialization errors. Later I checked that Spark had
been built on Scala 2.12.8 and I switched on it, and everything works well now.
Isn't it an error that Spark 2.4.1 doesn't support other minor versions?
