Alexander Rojas commented on MESOS-2186:
----------------------------------------
So, I was looking into this, and It is definitely a zookeeper client bug. When
we call {{zookeeper_init}}, the zookeeper client ends up calling a function
called {{getaddrs}} which goes through the list of given hosts calling
[{{getaddrinfo}}|http://linux.die.net/man/3/getaddrinfo]. If any of the calls
fail, it marks the whole initialisation as failed.
Since there's no more information about failed initialisation given to the
caller, apart from the return value being null and {{errno}} being set to
{{EINVAL}}, mesos just aborts.
So, I guess the Idea would be to report a bug into the zookeeper project. The
question then is, what is the desired behaviour?
> Mesos crashes if any configured zookeeper does not resolve.

> Key: MESOS-2186
> URL: https://issues.apache.org/jira/browse/MESOS-2186
> Project: Mesos
> Issue Type: Bug
> Affects Versions: 0.21.0
> Environment: Zookeeper: 3.4.5+28-1.cdh4.7.1.p0.13.el6
> Mesos: 0.21.0-1.0.centos65
> CentOS: CentOS release 6.6 (Final)
> Reporter: Daniel Hall
> Priority: Critical
> Labels: mesosphere
>
> When starting Mesos, if one of the configured zookeeper servers does not
> resolve in DNS Mesos will crash and refuse to start. We noticed this issue
> while we were rebuilding one of our zookeeper hosts in Google compute (which
> bases the DNS on the machines running).
> Here is a log from a failed startup (hostnames and ip addresses have been
> sanitised).
