Project development has moved to: https://github.com/mesos/myriad.
Myriad is a mesos framework designed for scaling YARN clusters on Mesos. Myriad can expand or shrink one or more YARN clusters in response to events as per configured rules and policies.
The name Myriad means, countless or extremely great number. In context of the project, it allows one to expand overall resources managed by Mesos, even when the cluster under mesos management runs other cluster mangaers like YARN.
