Sumit Mohanty commented on AMBARI-9363:
---------------------------------------
Patch looks good to me. Its a good change to have so that custom services are
step closer to be completely self contained. +1
> role_command_order.json should not be at stack level

> In current stack definitions, role_command_order.json is at the stack level.
> For example: HDP/2.2/role_command_order.json
> Service definitions are all nicely separated into different directories, like
> HDP/2.2/services/{HDFS|YARN}, but not the role_command_order. It would be
> neater to separate role_command_order per service and would be very useful
> while adding a new service to Ambari.
> Looking for something as below,
> - HDP/2.2/services/HDFS/role_command_order.json
> - HDP/2.2/services/YARN/role_command_order.json
> Ambari server while starting should merge all role_command_order.json and
> create dependencies accordingly.
> This is extremely useful for custom services which are potentially added
> after the cluster install.
