> Ambari stores rack info for hosts in DB based on ClusterTopology data received in Blueprint request. However, it is not necessary that blueprint would contain correct data. After commission/decommission operation, topology should contain updated rack based topology.
> Hence, we should provide an option in UI to print rack based datanodes as a topology.
