Build Status

Myriad is a Mesos framework designed for scaling a YARN cluster on Mesos. Myriad can expand or shrink the resources managed by a YARN cluster 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 managers like YARN.

Please note: Myriad is not yet production ready. However, the project is rapidly progressing with some very useful features.

Getting started
