how to enable stop services in parallel

[#1]

in our ambari cluster

when we stop some services ,

then we sow that the first service progress is stoping

but the other services are pending

how to enable all stop services to be stop in parallel ?

@Michael Bronson,

This is because of dependency between the services. These are defined in role_command_order.json. If there is no dependency for the component it can run in parallel between the nodes. However in a particular node the execution will be sequential.

You can check the role_command_order.json for different services and their dependencies. Just run the command in ambari server to find all the json files.

find /var/lib/ambari-server/ -iname role_command_order.json

Thanks,

Aditya
