Bartek Plotka updated MESOS-4076:
---------------------------------
Description:
It would be nice to have simple QoS Controller module out-of-box in _Mesos_
(Similar to the _FixedResourceEstimator_).
As a result we will:
- enable simple QoS assurance and encourage users to use oversubscription
modules.
- present example QoS module for new developers.
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.
