The configuration options are somewhat different for yarn, then they are for MRV1. You probably want to generate the documentation for yarn
And then read through it about how to set up your cluster
There is documentation about setting up the capacity scheduler too. If you run into any issues then reply here and if the documentation needs to be cleaned up was can file a JIRA against the documentation. The documentation is kind of new so it would be good to get some real feedback on it.

which is FifoScheduler) and CapacityScheduler can be configured too.
