Hi All, I get a serialization error when I try submit a job to livy. I am not sure what I am doing wrong?
public class MyJob implements Job<String> { private final String *name*; private List<String> cols; private List<String> *tags*; public MyJob(String name, List<String> cols, List<String> tags) { this.name = name; this.cols = cols; this.tags = tags; } } and then I do something like this livy.submit(new MyJob("cat", Arrays.asList("hello"), new ArrayList<>())).get(); I get the following Exception java.util.concurrent.ExecutionException: java.lang.RuntimeException: org.apache.livy.shaded.kryo.kryo.KryoException: java.lang.NullPointerException Serialization trace: cols (com.hello.sample.jobs.MyJob) org.apache.livy.shaded.kryo.kryo.serializers.ObjectField.read(ObjectField.java:125) org.apache.livy.shaded.kryo.kryo.serializers.FieldSerializer.read(FieldSerializer.java:507) Thanks!
