Andrei Savu commented on WHIRR-332:
-----------------------------------

I believe that we need something like: whirr.templates.roles.${template-group}.hardware-id

> When setting up Hadoop, whirr.hardware-id is used in the configuration to set a single instance size/type for both nn,jt and dn,tt roles, but there are workloads that benefit from having a different instance size/type for each role.  This need is even greater for ensembles with Zookeeper and HBase.
> Without this, a small Whirr cluster underutilizes resources. 
> whirr.hardware-id should be a used to set a default instance size/type, and variations like whirr.${role}.hardware-id could be used to set size/type more specifically. This is a simple, obvious, and easy to implement mechanism to provide this functionality.
