Comment: was deleted
(was: I messed up my test, Flink 1.9.1 has the same problem. It's still only
compatible with Scala 2.12.7.)
> Flink 1.8 not working with Scala 2.12.8
> ---------------------------------------
>
> Key: FLINK-12461
> URL: https://issues.apache.org/jira/browse/FLINK-12461
> Project: Flink
> Issue Type: Bug
> Components: API / Scala
> Affects Versions: 1.8.0
> Reporter: Gaël Renoux
> Assignee: Aljoscha Krettek
> Priority: Major
>
> When using 1.8 with Scala 2.12.8 and trying to parse a scala.Map (not a
> java.util.Map), I get a: java.lang.ClassNotFoundException:
> scala.math.Ordering$$anon$9
> To reproduce:
> - start with the Scala Maven archetype
> (org.apache.flink:flink-quickstart-scala:1.8.0)
> - in the POM, set the scala.version to 2.12.8 and the scala.binary.version
> to 2.12
> - in StreamingJob, add: env.fromElements[Map[String, Int]]()
> It works with Scala 2.12.7 (well, without putting anything in the job, it
> fails with "No operators defined in streaming topology", which is expected).
> I suspect this is linked to the binary incompatiblity of 2.12.8 with 2.12.7
> (see the release note of 2.12.8), so compiling Flink with 2.12.8 instead of
> 2.12.7 might be enough (although it might stop working with 2.12.7?)
