> CLI - Add a command to start controller services
> ------------------------------------------------
>
> Key: NIFI-5027
> URL: https://issues.apache.org/jira/browse/NIFI-5027
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Tools and Build
> Reporter: Pierre Villard
> Assignee: Bryan Bende
> Priority: Major
>
> When importing a versioned process group from the registry, all the
> components will be stopped (in case of update, only the newly added
> components will be stopped). We already have a command pg-start to start a
> process group, but it will fail if the process group relies on controller
> services that should be enabled first.
> A new command like pg-enable-cs could be added, or just add a parameter/flag
> to the pg-start command.
> Things to consider:
> * there can be a dependency chain between the controller services requiring
> to start the controller services in the right order. Example: the avro schema
> registry CS and a reader/writer CS depending on the schema registry CS.
> * there can be a CS defined at pg level that is not referenced by any
> component inside the pg but that would need to be started nevertheless.
> Example: the distributed map cache server CS.
