Vinod Kone updated MESOS-644:
-----------------------------
Issue Type: Bug (was: Task)
> Slave doesn't correctly handle checkpointed terminal update whose ack doesn't
> reach the executor
> ------------------------------------------------------------------------------------------------
>
> Key: MESOS-644
> URL: https://issues.apache.org/jira/browse/MESOS-644
> Project: Mesos
> Issue Type: Bug
> Reporter: Vinod Kone
> Assignee: Vinod Kone
> Fix For: 0.14.0
>
>
> This is the scenario.
> Slave dies after checkpointing a terminal update but before the ACK reached
> the executor.
> Recovered slave/status update manager retries the update and cleans it up
> after it gets an ACK from the scheduler.
> When the executor re-registers after this point, it still has a pending
> update but the slave cannot find the executor for this update because the
> task is completed! Currently the slave forwards this update to the SUM anyway
> but never acks the executor.
