PUT /cm/deployment
Apply the supplied deployment description to the system. This will
create the clusters, services, hosts and other objects specified in
the argument. This call does not allow for any merge conflicts. If
an entity already exists in the system, this call will fail.
You can request, however, that all entities in the system are deleted
before instantiating the new ones.
You may specify a complete or partial deployment, e.g. you can provide
host info with no clusters. However, if you request that
the current deployment be deleted, you are required to specify at
least one admin user or this call will fail. This is to protect
you from creating a system that cannot be logged into again.
If there are any errors creating (or optionally deleting) a deployment,
all changes will be rolled back leaving the system exactly as it was
before calling this method. The system will never be left in a state
where part of the deployment is created and other parts are not.
If the submitted deployment contains entities that require Cloudera
Enterprise license, then the license should be provided to Cloudera Manager
before making this API call.

prevents unnecessary re-replication which could occur if decommissioned.
