I went through the preview instructions and everything worked great. For those who would like to write a java/scala client, which spark-core version should we use via maven? I couldn’t find the jars in the Hortonworks maven repo, is one there? I was getting serialization errors with some of the spark classes when using “org.apache.spark” % “spark-streaming_2.10” % “1.0.2”. Should I use 1.0.1 from apache?
