Github user manuzhang commented on the issue: https://github.com/apache/incubator-gearpump/pull/223 We also do an extra check for cycle here. Can it be removed ? ```scala if (dag.hasCycle()) { LOG.warn(s"Detected cycles in DAG of application $name!") } val indices = dag.topologicalOrderWithCirclesIterator.toList.zipWithIndex.toMap ```
