Jan Schlicht commented on MESOS-4025:
-------------------------------------
Hey, I've seen that you posted a review for that. I really appreciate the work
you done on this, but unfortunately there was already some work done, it just
took a bit to find a shepherd for this. Your approach to use {{MockDocker}} is
the same that I've chosen, so I'd really appreciate if you'd take a look at my
review request for this ticket and comment on this. Again, sorry that we both
basically did the same work and that my review request is online just now.
> SlaveRecoveryTest/0.GCExecutor is flaky.
