Hi Andrii, TaskStatus includes the task's labels [1], so what you're trying to do should work.
BTW, we recently wrote up some suggestions on how to write highly available frameworks. The docs will be on the website the next time it is refreshed; in the mean time, you can find them here: https://reviews.apache.org/r/41896/diff/8#1 Neil [1] https://github.com/apache/mesos/blob/master/include/mesos/mesos.proto#L1162 On Fri, Jan 22, 2016 at 6:49 AM, Andrii Biletskyi <andrii.bilets...@stealth.ly> wrote: > Hi, > > I'm using Mesos 0.25.
