You can set configurations at the blueprint level (to apply to all host_groups) and you can also set configurations in the host_groups element to set configurations for that host_group.
Will that help? Or will it just mean you will have to have a host_group that you have to apply per host? https://cwiki.apache.org/confluence/display/AMBARI/Blueprints#Blueprints-Configurations On Thu, Jun 5, 2014 at 12:58 AM, Qing Chi 79624 <c...@vmware.com> wrote: > Hi guys, > I want to use specific data dir on each host.
