Re: [ERROR] [TaskSetManager] Task 2.0 in stage 10.0 had a not serializable result

Chiming in a bit. Looking at the serialization error, it looks like we are just one little step away from getting this to work. Noelia, what does your synthesized data look like? All data that is processed by Spark needs to be serializable. At some point, a non-serializable vector object showing

Pat, you are absolutely right! I increased the sleep time and now the integration test for handmade works perfectly. However, the integration test adapted to run with my tiny app runs into the same problem I've been having with this app: [ERROR] [TaskSetManager] Task 1.0 in stage 10.0 (TID 23)
