New service user for custom service
Hi
We are adding a new custom service in our Ambari stack and would like to
run the service as a new service user. I have seen that for services like
Zookeeper, the zookeeper user is configured in zookeeper-env.xml which
would show up in the configuration recommendations page in UI and Ambari
would create the user if not already present.
However for the new service that we are adding, there is no configuration
folder as there are no configs for this service. Can you please guide me on
where to configure this new user so that it shows up in configuration
recommendation page ?
Thanks

HI Sandeep, you can generate a config-type to store the user but not
actually save the config file to the local file system.
Thanks,
Alejandro

Thanks for the reply Janne
I have tried out even that route of adding one xml file in the
configuration folder and the USER property that you mentioned in the file.
But the framework is throwing an exception when it is setting empty configs
as there are no other configs apart from the USER property in the xml file.
So trying to figure out if there is any other place where we can configure
this USER property

ripped this out from how zk service was done. I think a way it works is
if property-type is USER then that instructs ambari to actually create that
user.

Afaik you need to add that configuration you mentioned. That's something
I'm doing[1] in Spring Cloud Dataflow plugin for ambari. Then if you're
executing a process you need to reference[2] that user. I think I also
ripped this out from how zk service was done. I think a way it works is
if property-type is USER then that instructs ambari to actually create that
user.
