In this recipe, we will define roles and assign them weights to prioritize some frameworks over others.
Defining roles and resources
How to do it...
Roles are part of the resources definition. We define resources and roles for each agent. For example, we want to change the default port range to 51000-52000 and the offered disk space to 4096 GB. To do this, we need to explicitly override the default values. You need to edit /etc/mesos-slave/resources and put the desired resources:
echo 'disk(*):4096; ports(*):[51000-52000]'> /etc/mesos-slave/resources
In a similar way, we can define other resources such as CPUs, memory, or GPUs just by adding the corresponding entry. The preceding configuration defines the default...
