[jira] [Created] (SPARK-27487) Spark - Scala 2.12 compatibility

Vadym Holubnychyi created SPARK-27487:
-----------------------------------------

             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?
