Adam B commented on MESOS-2962:
-------------------------------
bq. If the DNS cannot resolve the hostname-to-IP for a slave node, we correctly
return an Error object, but we then fail with a segfault.
Could you please provide more information on the original error? Can you
include the log/stacktrace?

> Key: MESOS-2962
> URL: https://issues.apache.org/jira/browse/MESOS-2962
> Project: Mesos
> Issue Type: Bug
> Components: slave
> Affects Versions: 0.22.1
> Reporter: Marco Massenzio
> Assignee: Marco Massenzio
> Labels: tech-debt
>
> If the DNS cannot resolve the hostname-to-IP for a slave node, we correctly
> return an {{Error}} object, but we then fail with a segfault.
> This code adds a more user-friendly message and exits normally (with an
> {{EXIT_FAILURE}} code).
> For example, forcing {{net::getIp()}} to always return an {{Error}}, now
> causes the slave to exit like this:
> {noformat}
> $ ./bin/mesos-slave.sh --master=10.10.1.121:5405
> WARNING: Logging before InitGoogleLogging() is written to STDERR
> E0630 11:31:45.777465 1944417024 process.cpp:899] Could not obtain the IP
> address for stratos.local; the DNS service may not be able to resolve it: >>>
> Marco was here!!!
> $ echo $?
> 1
> {noformat}
