Hello,
To control the layout of components on the cluster, you would contribute your logic to the
stack_advisor.py script in the stack-version which contains your service. For example NameNode
placement wrt ResourceManager etc. can be seen at https://github.com/apache/ambari/blob/trunk/ambari-server/src/main/resources/stacks/HDP/2.0.6/services/stack_advisor.py#L1392

Depending on the type of component (Master, Slave, Client) and its cardinality, the component
gets distributed in the layout by the stack-advisor.
Regards,
Srimanth

Subject: disable installation of different conponents of the same service on the same node

Hi all, I'm developing a custom service for Ambari.
Is there a way to disable the installation of different components of
the same service on the same node?
For example prevent a slave component installation if a master component
of the same service is already configured on a single node of the cluster?
Thank you for your support.
Bests.
Mauro
