The Myriad environment is established by running an initial application for the resource manager. This initial application name is specified in the yarn-site.xml file with the the yarn.resourcemanager.hostname property and the value, <app-name>.<framework>.mesos.
For example, if the value of yarn.resourcemanager.hostname property is rm.marathon.mesos:

marathon - The Myriad framework.
