> Key: AMBARI-10750
> URL: https://issues.apache.org/jira/browse/AMBARI-10750
> Project: Ambari
> Issue Type: Task
> Components: ambari-server, blueprints
> Affects Versions: Ambari-2.1
> Reporter: John Speidel
> Assignee: John Speidel
> Fix For: Ambari-2.1

> Attachments: AMBARI-10750.patch

>
> 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.
