             Summary: Create simple LoadQoSController which will evict revocable executors when system load is too high.
                 Key: MESOS-4076
                 URL: https://issues.apache.org/jira/browse/MESOS-4076
             Project: Mesos
          Issue Type: Task

It would be nice to have simple QoS Controller module  out-of-box in _Mesos_(Similar to the _FixedResourceEstimator_). The idea is to implement _LoadQoSController_ which will monitor system load and evict all revocable executors when the load is above configured threshold.

In implementation, it will support two configurable thresholds: system load average 5min and 15min. System load 1 min will be ignored, since it could be misleading signal when temporary fluctuations appears.

We could also add description to the oversubscription.md doc,
