-----------------------------------
Sprint: Q2'14 Sprint 2
> Unnecessary queuing of status update acknowledgments in the scheduler drive.r
> -----------------------------------------------------------------------------
>
> Key: MESOS-1408
> URL: https://issues.apache.org/jira/browse/MESOS-1408
> Project: Mesos
> Issue Type: Bug
> Components: c++ api, framework, java api, python api
> Affects Versions: 0.19.0
> Reporter: Benjamin Mahler
> Assignee: Benjamin Mahler
> Fix For: 0.19.0
>
>
> We currently 'defer' in order to acknowledge processed status updates in the
> scheduler driver.
> This is unfortunate because it adds unnecessary delay and unnecessary
> retries, especially when the scheduler's queue is backed up!
> It is sufficient to use 'aborted' to see if we can send a status update.
> Ideally there would be proper locking on this variable rather than the use of
> 'volatile', but since we're mostly concerned about the driver aborting on the
> same thread as the status update was processed, I've left it as is.
> This will also be beneficial when we send status updates through the master
> as is required for MESOS-1389 and the other reconciliation tickets.
