In this recipe, you will learn how to turn on oversubscription, a module that enables Mesos to make use of allocated but unused resources.
Mesos comes with the basic implementation of the resource estimator and QoS controller, provided the estimator returns a fixed value each time. The QoS controller is a little bit more advanced because it monitors the system and revokes all slack resources when the system load is too high:
system load is too high: echoorg_apache_mesos_FixedResourceEstimator> /etc/mesos-slave/resource_estimator echoorg_apache_mesos_LoadQoSController> /etc/mesos-slave/qos_controller echo 60secs > /etc/mesos-slave/qos_correction_interval_min cat<< EOF > /etc/mesos-slave/modules { "libraries":[ { "file":"/usr/lib/mesos/modules/libload_qos_controller.so", "modules":{ "name":"org_apache_mesos_LoadQoSController", "parameters":[ { "key":"load_threshold_5min", "value":"6" }, { "key...
