--------------------------------------
Resolution: Duplicate
> aurora_admin's perform_maintenance_hosts command doesn't fail on unknown hosts
> ------------------------------------------------------------------------------

> Key: AURORA-494
> URL: https://issues.apache.org/jira/browse/AURORA-494
> Project: Aurora
> Issue Type: Bug
> Components: Client, Scheduler
> Reporter: David Robinson
> Priority: Minor
>
> If you feed the aurora_admin's perform_maintenance_hosts command a filename
> containing a list of random strings (supposedly FQDNs) it'll happily drain
> those random strings!
> {noformat}
> $ cat drain.txt
> my-imaginary-server
> your-imaginary-server
> any-imaginary-server
> $ aurora_admin perform_maintenance_hosts --filename=drain.txt my-cluster
> INFO] Ending maintenance for: set(['my-imaginary-server',
> 'your-imaginary-server', 'any-imaginary-server'])
> INFO] Response from scheduler: OK (message: None)
> INFO] Maintenance status for: set(['my-imaginary-server',
> 'your-imaginary-server', 'any-imaginary-server'])

> It'd be great if there was actually some validation that notified a user if a
> host wasn't valid.
> This tripped me up because I was using hostnames instead of the FQDNs. Easy
> mistake to make, difficult to troubleshoot when everything says 'OK'.
