> 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.
