Review request for mesos, Benjamin Hindman and Vinod Kone.
Bugs: MESOS-1409
https://issues.apache.org/jira/browse/MESOS-1409
Repository: mesos-git
Description
-------
Currently status update acknowledgments are sent directly from the scheduler
driver to the slave.
However, in order to provide correct reconciliation of tasks, the master needs
to hold on to terminal unacknowledged tasks to ensure that it can correctly
identify these until the framework receives the terminal update. Without this,
we are susceptible to MESOS-1389.
In 0.19.0, the master was updated to handle acknowledgements. Now in 0.20.0, we
can safely send the acknowledgements through the master.
