(was: Use a treemap instead of hashmap in in AM.getAssignmentByTable used in balancer) There are few more changes that we can do here - Currently two different balancer objects are created in AssignmentManager and HMaster. Unify them - balancer.randomAssignment() is getting called once but based on whether the existingplan is null or if it is a force plan we either use the randomplan or not. Ideally if we are extending a new balancer then randomAssignment will be called but later the plan given by randomAssignment may not be used.
