> API based (blueprint) cluster provisioning modifications and enhancements which will provide for more flexible, scalable and robust cluster provisioning.
> This will include API and backend changes.
> - Allow a host count to be specified in the cluster creation template instead of host names.  This is documented in https://issues.apache.org/jira/browse/AMBARI-6275
> - Allow cluster creation or scaling to be started via the REST API prior to all/any hosts being available.  As hosts register with Ambari server they will be matched to request host groups and provisioned according to the requested topology
> - Allow host predicates to be specified along with host count to provide more flexibility in matching hosts to host groups.  This will allow for host flavors where different host groups are matched to different host flavors
> - Break up the current monolithic provisioning request into a request for each host operation.  For example, install on host A, start on host A, install on hostB, etc.  This will allow hosts to make progress even when another host encounters a failure.
> This Jira will be updated shortly with more information on this extensive set of enhancements and changes.
