@rnettleton, I was following the same steps that you have mentioned but if we go with this approach, we need to come up with all possible hostgroup (component maping) combinations ahead of time. I was trying to find a way to overcome by adding new hostgroup to existing BP (not modifying any of the existing BP structure). May be we shall consider this as a feature request?

There are only few SLAVE components for a stack (DN, NM, ACCUMULO_TSERVER, FLUME_HANDLER, METRICS_MONITOR, HBASE_REGIONSERVER, PQS, SUPERVISOR). I am trying to understand if some of the components can be grouped seperately to balance the load (for e.g., CPU centric components can be isolated). What is the general guidance, deployment practice used in the field?

Thanks Ali Bajwa. My question is how one could possibly mutate blueprint to add hostgroups dynamically instead of playiing with only fixed set created duirng cluster create step.

Let's say if I have 20+ nodes to deploy "SLAVE" components for the services HDFS, HIVE, HBASE and OOZIE, what is the general guidance on SLAVE component placement? Should all node contain all SLAVE components or is it better to isolate the SLAVE components? If the answer is latter, are there any guidance on doing this?

Blueprint supports SLAVE node expansion through "add host" API. We could provide blueprint and hostgroup name to add host API and the API takes care of replicating hostgroup components (from corresponding Blueprint) in the new set of hosts. In scenario where if only DATANODE" needs to be expanded, it is not possible unless the BP has a hostgroup that has only "DATANODE" component.

I would like to create a host specific configuration group to limit some changes to core-site configuration on a specif host. How can I achive this using API?
