Hi Guys, 

we have the situation that wenn we remove a host from the zookeeper cluster mesos-agents will not start. I think this is wrong and the lib should just try the next host. 

Here are my logs:

_HOST__LIST has one host that is invalid. 

 

to reproduce build from master from 08.10.2018 and run mesos-agent.sh --master=zk://somehostThatDoesNotExist,validHosts

 

The same issue is there for 1.3.2
