Bill Farner commented on AURORA-1228:
-------------------------------------

My guess is that the end-to-end tests are passing, but you're being bitten by 
AURORA-1204 + https://reviews.apache.org/r/33658/.  Can you try destroying your 
vagrant machine and re-running the tests?

> Use explicit status update acknowledgements to improve driver throughput.

> Mesos 0.22.0 is released and includes the ability for schedulers to perform 
> explicit acknowledgments of status updates.
> This allows schedulers to process status updates asynchronously from the 
> driver thread. Updates can then be processed in batches to reduce the 
> per-update processing overhead. These should help provide substantial 
> improvements to the schedulers update processing throughput.
> I've placed this under the GC executor retirement effort, per AURORA-1047.
