> OrgQueue for easy CapacityScheduler queue configuration management

> Project: Hadoop YARN
> Issue Type: New Feature

> Assignee: Min Shen
> Attachments:
> OrgQueueAPI-BasedSchedulerConfigurationManagement_v2.pdf,

> The current xml based configuration mechanism in CapacityScheduler makes it
> very inconvenient to apply any changes to the queue configurations. We saw 2
> main drawbacks in the file based configuration mechanism:
> # This makes it very inconvenient to automate queue configuration updates.
> For example, in our cluster setup, we leverage the queue mapping feature from
> YARN-2411 to route users to their dedicated organization queues. It could be
> extremely cumbersome to keep updating the config file to manage the very
> dynamic mapping between users to organizations.
> # Even a user has the admin permission on one specific queue, that user is
> unable to make any queue configuration changes to resize the subqueues,
> changing queue ACLs, or creating new queues. All these operations need to be
> performed in a centralized manner by the cluster administrators.
> With these current limitations, we realized the need of a more flexible
> configuration mechanism that allows queue configurations to be stored and
> managed more dynamically. We developed the feature internally at LinkedIn
> which introduces the concept of MutableConfigurationProvider. What it
> essentially does is to provide a set of configuration mutation APIs that
> allows queue configurations to be updated externally with a set of REST APIs.
> When performing the queue configuration changes, the queue ACLs will be
> honored, which means only queue administrators can make configuration changes
> to a given queue. MutableConfigurationProvider is implemented as a pluggable
> interface, and we have one implementation of this interface which is based on
> Derby embedded database.
> This feature has been deployed at LinkedIn's Hadoop cluster for a year now,
> and have gone through several iterations of gathering feedbacks from users
> and improving accordingly. With this feature, cluster administrators are able
> to automate lots of thequeue configuration management tasks, such as setting
> the queue capacities to adjust cluster resources between queues based on
> established resource consumption patterns, or managing updating the user to
> queue mappings. We have attached our design documentation with this ticket
> and would like to receive feedbacks from the community regarding how to best
> integrate it with the latest version of YARN.
