Hi Spark Users, I'm trying to read and process an Avro dataset using the interactive spark scala shell. When my pipeline executes I get the ClassNotFoundException pasted at the end of this email. I'm trying to use the Generic Avro API (not the Specific API).
Here's a gist of the commands I'm running in the spark console: https://gist.github.com/jlewi/2c853edddd0ceee5f00c Here's my registrator for kryo. https://github.com/jlewi/cloud/blob/master/spark/src/main/scala/contrail/AvroGenericRegistrator.scala Any help or suggestions would be greatly appreciated. Thanks Jeremy Here's the log message that is spewed out. 14/05/24 02:00:48 WARN TaskSetManager: Loss was due to java.lang.ClassNotFoundException java.lang.ClassNotFoundException:
