Stephan Erb commented on AURORA-1811:
-------------------------------------

[~a-nldisr] to clarify: Do you have a workaround in place, or do you need a fix for this in the next version. If not, we could resolve this when dropping the deprecated `production` code in 0.18.

>             Project: Aurora
>          Issue Type: Bug
>          Components: Client, Maintenance, SLA
>    Affects Versions: 0.16.0
>         Environment: Vagrant image - Ubuntu, Centos 7.2
>            Reporter: Rogier Dikkes
>            Priority: Minor
>              Labels: client, features, sla
>             Fix For: 0.17.0

> We recently had to patch hosts, in our situation we have a couple of services that run less than 2-5 instances with production = true and tier = preferred as provided in the default example documentation. 
> As we understood host_drain is not configurable to set the minimum job instance count, the default is 10. We tried to compile a list of hosts with aurora_admin sla_list_safe_domain that are running these services to feed host_drain with an unsafe_hosts_file. 
> When we ran the aurora_admin sla_list_safe_domain --min_job_instance_count=2 devcluster 95 1m the scheduler returns: 
>  INFO] Response from scheduler: OK (message: )
> As if there are no hosts. We tried to change the percentage and duration to see if anything was returned but we never receive an different response.
> To ensure that the client is not the cause we used the 0.16.0 client against an 0.14.0 cluster, this cluster reports hosts that are safe to kill without violating job sla's. 
> To ensure its not a faulty cluster setup on our part we started the vagrant sandbox, started an task with 3 instances with tier = preferred and production = True.
> commands used:
> aurora_admin sla_list_safe_domain --min_job_instance_count=2 devcluster 20 50m
> aurora_admin sla_list_safe_domain --min_job_instance_count=2 devcluster 90 5m
> With -l or with time and percentage variations never changes the outcome.
> Changing the instance_count to a higher number does not change output either.
