Subject Re: [DISCUSS] Remove dependency on ZooKeeper for leader election?
Date Wed, 19 Aug 2015 10:18:24 GMT
It seems like there's some movement in Mesos to get rid of Zookeeper / make
it replaceable:
https://issues.apache.org/jira/browse/MESOS-1806

With this it could (maybe maybe) make sense to drop ZK for leader election
(but then there's at least  thermos announcment still around in ZK, isn't
it?)
