Klaus Ma updated MESOS-4303:
----------------------------
Description:
Currently, if one famework launched tasks in all resources, the other framework
has to wait those tasks completed to get deserved resources. That's un-fair to
the new framework, there're several EPICs on such case but still can not
resolve it:
- Quota: balance resouces based on un-allocated resources; the used
resources can not be reclaim back when new framework registered
- Optimistic Offer Phase 1 (oversubscription of reservation): the un-used
reserved resources can be used by the new framework; but still can not reclaim
un-reserved resources back.
- Optimistic Offer Phase 2: in phase 2, all resources are offered to all
framework; besides resources conflict, it also need to re-shuffle resources if
one framework over occupied.
The target of this EPIC is to
1. Enhance DRF to identify which resources should be reclaim
2. Define the protocol between Mesos & Framework to reclaim resources
gracefully
To keep the compatibility, this feature is controlled by master paramenter,
e.g. --enable-reclaim.
