Joe Stein commented on KAFKA-287: --------------------------------- I run Kafka in production using Scala 2.9.1 changing build.properties and creating a new build I run sbt 11.2 for all of my code but use the existing sbt in the Kafka project for building kafka. KAFKA-134 tries to address an upgrade to 0.10.1 which I tried once but ran into an issue. we should look at KAFKA-134 and making it be 11.2 (should not be much more than what was already in 0.10.1 changes) do you want to take a look into KAFKA-134 ? I can review when you are done.. I think this ticket though is covered in KAFKA-134 changes. the workaround is exactly what you did, change build.properties to 2.9.1 and rebuild. works great just some warnings otherwise have no issue in production > Running a consumer client using scala 2.8 fails > ----------------------------------------------- > > Key: KAFKA-287 > URL: https://issues.apache.org/jira/browse/KAFKA-287 > Project: Kafka > Issue Type: Bug > Environment: Java 1.6, OS X > Reporter: Elben Shira > > Built the kafka library using the instructions found in the README. My client > uses scala 2.9.1, sbt 0.11. My consumer client has this snippet of code: > https://gist.github.com/a35006cc25e39ba386e2 > The client compiles, but running it produces this stacktrace: > https://gist.github.com/efeb85f50402b477d6e0 > I think this may be because of a bug found in scala 2.9.0 (though I'm not > sure if it was present in scala 2.8.0): > https://issues.scala-lang.org/browse/SI-4575 > To get around this, I built the kafka library using scala 2.9.1 (by changing > build.properties). -- This message is automatically generated by JIRA.
