> Key: MESOS-305
> URL: https://issues.apache.org/jira/browse/MESOS-305
> Project: Mesos
> Issue Type: Improvement
> Reporter: Vinod Kone
> Assignee: Benjamin Mahler
> Priority: Critical
> Fix For: 0.13.0
>
>
> With the recent changes in the master detecter code, we no longer send
> 'NoMasterDetected' to the scheduler driver, which in turn means the
> 'disconnected' scheduler callback is never invoked.
> At Twitter this manifested as a spew of LOST tasks whenever a master failover
> happens. This is because the scheduler holds on to offers for a while and
> never knows about the invalidity of offers, until after tasks are launched.
> Though this is a race, it is ideal to minimize this window as much as
> possible by informing the scheduler of the master failover.
