Thanks for preparing the release. Is the binary release compiled with java 7? Got the following error using a java 6 runtime.
bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic test --from-beginning Exception in thread "main" java.lang.UnsupportedClassVersionError: kafka/javaapi/consumer/ConsumerConnector : Unsupported major.minor version 51.0 at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClassCond(ClassLoader.java:631) at java.lang.ClassLoader.defineClass(ClassLoader.java:615) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:141) at java.net.URLClassLoader.defineClass(URLClassLoader.java:283) at java.net.URLClassLoader.access$000(URLClassLoader.java:58) at java.net.URLClassLoader$1.run(URLClassLoader.java:197) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) at kafka.consumer.ConsoleConsumer$.main(ConsoleConsumer.scala:178) at kafka.consumer.ConsoleConsumer.main(ConsoleConsumer.scala) Should we release the binary in java 6 or java 7?
