> Deployment of a hadoop cluster can be modeled as the mapping of a stack definition to
a set of host while satisfying placement constraints. A stack definition refers to the description
of various services that comprise a hadoop stack (e.g. HDP-1.2.1), components associated with
the services, and configuration properties. A set of available hosts is specified through
a host-manifest that lists the available hosts and relevant properties/characteristics of
each host. A cluster blueprint is specification of a hadoop stack mapped to a set of hosts.
Mapping to a host can be a direct mapping - e.g. deploy this component X on host Y or a host
can be specified as a set of requirements which is used to select the most appropriate host(s)
from a host-manifest.
