Jonathan Hung commented on YARN-5949:
-------------------------------------
Thanks [~xgong] for the review.
Right now the default policy is DefaultConfigurationMutationPolicy. I was
thinking the policy would be enforced in MutableCSConfigurationProvider instead
of the REST API, so if they want to use the queue admin-based policy they can
just configure {{yarn.scheduler.configuration.mutation.policy.class}} to
QueueAdminConfigurationMutationPolicy.
> Add pluggable configuration policy interface as a component of

> This will allow different policies to customize how/if configuration changes
> should be applied (for example, a policy might restrict whether a
> configuration change by a certain user is allowed). This will be enforced by
> the MutableCSConfigurationProvider.
