Can we really support a > version if we don't test it? > * New clients library is written in Java and won't be affected. It also has > received a lot of work and it's much improved since the last release. > * It was released 4 years ago, it has been unsupported for a long time and > most projects have dropped support for it (for example, we use a different > version of ScalaTest for Scala 2.9) > * Scala 2.10 introduced Futures and a few useful features like String > interpolation and value classes. > * Doesn't work with Java 8 (https://issues.apache.org/jira/browse/KAFKA-2203). > Vote thread: http://search-hadoop.com/m/uyzND1DIE422mz94I1 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
