Hi Satya,
Take a look at the ambari-server/src/main/resources/role_command_order.json This json structure is used to build the dependency graph between components. Every stack overrides this file to add order between new components that the stack introduces, so that the base copy of this file remains unchanged. In your case, if you add INSTALL time or START time dependencies between service2 to service1 components, Ambari will re-order the commands automatically. Note: Format of the keys in the json is "ComponentName"-"Command" (Commands: START, INSTALL, UPGRADE, SERVICE_CHECK).

How can I specify the dependency or order in which the services should be installed. Thanks, Satya.
