> Capacity scheduler is widely used in Hadoop clusters.
> Its configuration is as much easy to understand as complicated to define,
> consisting as filling a XML with some "ahem" notions :
> - "all" rights are represented by "*" (normal) but "no" rights are
> represented by " "
> - ACLs works only by extending them, not reducing : if root queue is set to
> all (default), no ACL will be considered at all
> A UI should be provided to abstract those concepts, as well as define more
> easily the queues weights, using sliders
> Additionally, if you forget to check yarn.acl.enabled in the resourcemanager
> there should be a warning about scheduler ACL rules
