Benjamin Ruland commented on AMBARI-20136:
------------------------------------------
[~sumitmohanty]: Can you please explain, why you removed the "supported"
attributes from RANGER in your change. From the description it would make sense
to set the "required" attribute, but not remove the capability.
> Services should be able to specify that credential store is always enabled

> At this point, credential store can be enabled or disabled for a service.
> Some services, such as Ranger and LogSearch should be able to indicate that
> CS cannot be disabled. The eventual goal is to always have CS enabled for all
> services that support credential store.
> Current metainfo.xml has the following section
> {code}
> <credential-store>
> <supported>true</supported>
> <enabled>false</enabled>
> </credential-store>
> {code}
> We need to add a notion of required. A third element called "required" may be
> added. We can potentially, create an enum for a new field "supportType" and
> collapse "supported" and "required" but that, while succinct, does not help
> much in readability.
> {code}
> <credential-store>
> <supported>true</supported>
> <required>false</required>
> <enabled>false</enabled>
> </credential-store>
> {code}
> The above means, CS is supported, not required, and not enabled. "false" is
> the default for *required*.
> For services that require CS support
> {code}
> <credential-store>
> <supported>true</supported>
> <required>true</required>
> <enabled>true</enabled>
> </credential-store>
> {code}
> Service create logic should set the CS-enabled flag to be true if *required*
> is true independent of what *enabled* says. *required* flag is not needed in
> the service resource REST API but the stacks API should provide access to
> this flag.
> API to disable CS should throw an error if *required* is true.
