Vinod Kone created MESOS-469:
--------------------------------
Summary: Scheduler driver should call disconnected on master
failover
Key: MESOS-469
URL: https://issues.apache.org/jira/browse/MESOS-469
Project: Mesos
Issue Type: Bug
Reporter: Vinod Kone
Assignee: Vinod Kone
Currently the driver only calls disconnected() when it gets NoMasterDetected()
message.
This means, during a master failover the driver only gets NewMasterDetected()
and hence the frameworks are in dark about this disconnection until they
re-register with the master.
At Twitter, we have seen this window to be as large as ~5s. So it would be nice
to give frameworks a heads up (disconnected()).
