Yes, it could be a classloader issue. Perhaps you need to pass the Spark task's ClassLoader to SpecificData? Find where your SpecificDatumReader is constructed, and pass it a SpecificData that was constructed with that ClassLoader. http://avro.apache.org/docs/current/api/java/org/apache/avro/specific/SpecificData.html#SpecificData(java.lang.ClassLoader) http://avro.apache.org/docs/current/api/java/org/apache/avro/specific/SpecificDatumReader.html#SpecificDatumReader(org.apache.avro.specific.SpecificData) Doug
