I was going through files I have in the system and I found some strange things that make me wonder about correct versioning. I am not sure but It may be the origin of the problems I see.
When I installed Samza I ran the following: git clone http://git-wip-us.apache.org/repos/asf/samza.git cd samza ./gradlew clean build I thought that this was getting the last stable version (0.9.1) but I have found that the compiled jars in my installation are named like this: samza-kv-rocksdb_2.10-0.10.0-SNAPSHOT.jar samza-core_2.10-0.10.0-SNAPSHOT.jar samza-api-0.10.0-SNAPSHOT.jar So as I understand it, I have samza 0.10.0 version installed and for scala 2.10. Is this correct? Kafka is installed with 2.9 scala. I am not sure if this is the conflicting element. Should I go to 2.10? Hadoop and yarn are version 2.6.0. Should I go to 2.7.1? I have tried to place in the lib folder the jar files generated in the samza compilation (2.10-0.10.0) and they show completely different messages. Now I see an error that ask for a new library that I cannot locate. Exception in thread "main" java.lang.NoClassDefFoundError: joptsimple/OptionSpec at org.apache.samza.job.JobRunner$.main(JobRunner.scala:39) at org.apache.samza.job.JobRunner.main(JobRunner.scala) Caused by: java.lang.ClassNotFoundException: joptsimple.OptionSpec at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:425) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:358) Do I have a versioning issue? Which library does this class belong to?
