Hi, I have a role:

“spark-base”  
role “spark-conf” depends on “spark-base”  
roles “install-workers”, “install-masters” depends on “spark-conf”

Here is dependency tree:

-“spark-base”  
-“spark-conf”  
-“spark-workers”, “spark-masters”

There is a declaration in my playbook:

- hosts: sparkworkers  
roles:
- “install-workers”

Is there any possibility run role “spark-conf” and not create separate playbook for this?

Hi, thank you. Sorry, I didn’t get the idea.  
Is it allowed to specify tag in dependency?
