Neil Conway commented on MESOS-3280:
------------------------------------

Fix for the race condition is here: https://reviews.apache.org/r/39325/

Note that the testing mock needs to be rethought (working on how to do this 
properly), and a few details need discuss (e.g., whether to use a backoff when 
retrying a failed coordinator election).

> In a 5 node cluster with 3 masters and 2 slaves, and ZK on each node, when a 
> network partition is forced, all the masters apparently lose access to their 
> replicated log. The leading master halts. Unknown reasons, but presumably 
> related to replicated log access. The others fail to recover from the 
> replicated log. Unknown reasons. This could have to do with ZK setup, but it 
> might also be a Mesos bug. 
> This was observed in a Chronos test drive scenario described in detail here:
> https://github.com/mesos/chronos/issues/511
> With setup instructions here:
