> While debugging some Flink on Mesos scheduling issues (tied to our use of
> Mesos quotas) we end up getting skewed offers that are useless fairly often.
> As we are not rejecting these offers fast enough and as we are not telling
> Mesos to not re-send for a long enough period, we end up not being able to
> schedule our job for upwards of an hour (~30 Mesos containers).
> The Fenzo default is to reject expired and unused Mesos offers after 120s,
> this can be overridden using their TaskScheduler builder. Additionally, Mesos
> allows us to override the time for which it won't re-send offers (default is
> 5s). We found that updating to reject more aggressively (every 1s instead of
> 120s) and keeping rejected offers away for longer (60s instead of 5s)
> dramatically increases our chances of scheduling our jobs on Mesos.
