Hi Stephan, I tried the solution with DeltaIteration#setSolutionSetUnManaged(), unfortunatelly the error is still there... Even when I try to run it with just one iteration... Also, I am not sure that the job can be broken into subparts in this particular case. Any other suggestions would be appr

Hello everyone, I am implementing a graph algorithm as part of a course and I will also add it to the Flink- Gelly examples. My problem is that I started developing it in the Gelly repository, which runs on flink 0.9. It works like a charm there, but in order to test in on a cluster to see its rea
