Vinod Kone commented on MESOS-2402:
-----------------------------------
As [~idownes] mentioned the flags have to be setup properly for exec to
function correctly. But that fix has nothing to do with the flakiness.
The real issue seem to be that there is a race between the
'containerizer->wait()' future being set to failed and the metric being
updated. This is because the thread running the test might check for the metric
value in between containerizer future being set but before the metric being
updated (see 'MesosContainerizerProcess::__destroy()'). The fix is to settle
the clock to ensure the metric is updated.
