Benjamin Mahler created MESOS-1389:
--------------------------------------
Summary: Reconciliation can send TASK_LOST before a terminal
update reaches the framework.
Key: MESOS-1389
URL: https://issues.apache.org/jira/browse/MESOS-1389
Project: Mesos
Issue Type: Bug
Affects Versions: 0.19.0
Reporter: Benjamin Mahler
Fix For: 0.19.0
There's an unfortunate case with reconciliation, where we end up sending
TASK_LOST first and then the slave sends the valid terminal status update.
When the slave re-registers with terminal tasks that have un-acked updates. The
master does not store these tasks. So while the slave still needs to send the
terminal status updates, the master will reply with TASK_LOST for
reconciliation.
We may need to ensure that all status update acknowledgements go through the
master to fix this.
