• Mesos Slave processes advertises all of a node’s resources (8 CPUs, 16 GB RAM) to Mesos Master.
• The YARN Node Manager is started as a Mesos Task. This task is allotted (4 CPUs and 8 GB RAM) and the Node Manager is configured to only advertise 3 CPUs and 7 GB RAM.
• The Node Manager is also configured to mount the YARN containers under the cgroup hierarchy  which stems from a Mesos task.

...

The following diagram shows a scenario where Mesos is used as the resource manager for the datacenter which allows both Mesos and YARN to schedule tasks on any node.

The following diagram gives an overview of how YARN can run along side Mesos:

Each node in the cluster has both daemons, Mesos Slave and YARN Node Manager, installed. By default, the Mesos slave daemon is started on each node and advertises all available resources to the Mesos Master.
