Bill Farner commented on AURORA-1192:
-------------------------------------
I'm following the code, and everything appears to be in order - the behavior
you describe is certainly unexpected. Can you post the initial section of the
scheduler's logs, where it outputs the command line argument values (taking
care to redact anything sensitive)?
[~SteveNiemitz] have you observed anything like this since you added this
patch? I assume you still rely on hostname overrides as well.

> Key: AURORA-1192
> URL: https://issues.apache.org/jira/browse/AURORA-1192
> Project: Aurora
> Issue Type: Bug
> Components: Scheduler
> Affects Versions: 0.7.0
> Environment: CentOS 7 x64, AWS
> Reporter: Will Farrington
>
> Our aurora-schedulers are configured to use the primary IP address of the
> host they run on with the {{-hostname}} flag.
> The announced serverset in zookeeper continues to use the local hostname.
> Here is an example of a {{get /aurora/scheduler/member_ID}} from ZK:
> {code}
> {"serviceEndpoint":{"host":"ip-172-18-60-156","port":8081},"additionalEndpoints":{"http":{"host":"ip-172-18-60-156","port":8081}},"status":"ALIVE"}
> {code}
> In this particular instance, the hostname doesn't resolve, resulting in the
> aurora-client being unable to talk to the aurora-scheduler, since the
> aurora-client is taking the host key out of the service endpoint.
> As best I can tell, this is the only spot where the supplied {{-hostname}}
> flag isn't utilized.
> The singleton candidate znodes in ZK however contain the hostname as supplied
> by the {{-hostname}} flag, as expected. Example {{get
> /aurora/scheduler/singleton_candidate_0000000018}}
> {code}
> 172.18.39.100
> {code}
