> It is important to safe guard against cycle graphs, when Ambari supports mpacks, custom services and service level role command order. Cycle graphs indicate circular dependencies that can cause Ambari enter an infinite loop while building stages, causing Ambari server to take up 100% CPU and large amount of memory.
