> Configuring the Capacity Scheduler can be done by either editing the
> capacity-scheduler.xml, or using the Mutation API to mutate the configuration
> step by step. Both of these methods require writing the relevant XML/JSON
> segments by hand and editing the quite hierarchical (and visual) queue
> hierarchy in a flat text file. YARN has all the required information
> published in its existing endpoints, and using the Mutation API it's possible
> to edit the queue hierarchy over time, either in batches or one-by-one.
> My proposal is to create a modern Javascript based UI, capable of:
> * visualizing the hierarchical queue structure, even a large one
> * presenting the relevant information about queues, their configured and
> calculated limits, actual states
> * providing a configuration UI to edit global scheduler and queue level
> properties
> * providing a way to add/edit/reorder placement rules
> * providing a way to add/edit/remove node labels
> * presenting some diagnostic options, by allowing downloading the relevant
> API responses for easier debugging
> * and presenting all of this in a modern, quick, easy to use UI, where
> config explanations and suggestions would help users configure YARN for their
> needs.
> This would make configuring Capacity Scheduler much more user friendly. I
> have been working on a UI, which I would like to integrate into YARN, as an
> optional UI to use if someone want to. The github repo tracking this is:
