Description

Assign.java has a piece of code to decide which placement framework to use (we have three today):

if (rulesMap == null && policyName == null && autoScalingConfig.getPolicy().getClusterPolicy().isEmpty())

Note that the presence of cluster preferences is not a criteria. So even if a user adds cluster preferences, they will not be respected unless a policy also exists.
