Been doing some testing with mesos 1.11.0 and zookeeper's "dynamic
reconfiguration" capability.
https://zookeeper.apache.org/doc/r3.6.3/zookeeperReconfig.html

Seems prima facie like mesos-master can handle a dynamic reconfig of the zk
ensemble up to the point
where a new set of participants has been added to the ensemble and the old
participants
have been demoted to non-voting followers.  But when the non-voting
follower processes are
terminated the master logs seem to indicate that the masters keep trying
and failing to reconnect
to the old zk leader, even though they've apparently received updates with
the new ensemble participants.

Anybody have any insight into this?
Any plans to support zk dynamic reconfiguration in the future?
Seems like it could make for easier O/S maintenance of one's master/zk
cluster hosts.
