------------------------------------------
Summary: Failover and recovery in presence of Quota
Key: MESOS-3865
URL: https://issues.apache.org/jira/browse/MESOS-3865
Project: Mesos
Issue Type: Epic
Components: allocation, master
Reporter: Alexander Rukletsov
Assignee: Alexander Rukletsov
The presence of quota in the cluster changes
Quota complicates master failover and recovery in several ways. The new master
should determine if it is possible to satisfy the total quota and notify an
operator in case it's not (imagine simultaneous failovers of multiple agents).
The new master should hint the allocator how many agents might reconnect in the
future to help it decide how to satisfy quota before the majority of agents
reconnect.
The allocator interface should be updated with some sort of recovery
information, which will allow it to react properly (e.g. seize offers and hold
off resources for some time).
