Yes Alexey, com.walmart.dataplatform.aorta.river.meta.Payload class is serializable.
Strange observation is overall spark job is successful but in executor logs we continuously observed this exception. As code is same across all nodes, how same code is working fine in one node and failing on another node with NotSerializableException.
