Flink Troubleshooting Documentation Required

I'm Running DC/OS on DigitalOcean and experiencing the same error as mentioned in Troubleshooting under "AWS Specific Config".
Could you please provide a solution for DigitalOcean?
This is what I'm getting on DigitalOcean, same as AWS:
2017-07-29 17:10:05,553 ERROR org.apache.flink.mesos.runtime.clusterframework.MesosApplicationMasterRunner - Mesos JobManager initialization failed
java.net.UnknownHostException: agentname: agentname: Name or service not known
at java.net.InetAddress.getLocalHost(InetAddress.java:1505)
@AGutan Did you solve it on DigitalOcean? Would be great if you could create a PR...
@joerg84 Well, I gave up searching for a solution for now, since the issue is not my main priority. Last thing I checked were similar settings to AWS on DigitalOcean.
The article suggests setting both of these to yes:
DNS resolution: | yes DNS hostnames: | yes
But I was unable to find similar settings on DigitalOcean.
@AGutan Can you help me reproduce the issue? Easiest is probably slack (chat.dcos.io)
@joerg84 I followed exactly this instructions: https://dcos.io/docs/1.10/installing/cloud/digitalocean/ Then added Flink from the UI (didnt change the configuration).
I also opened a StackOverflow thread two months ago: https://stackoverflow.com/questions/45391980/error-installing-flink-in-dcos/46262547
@AGutan and @joerg84 did this get resolved? I'd love to be able to close the issue :)
@judithpatudith the issue hasn't been resolved. At joerg84's request I reproduced the issue. Still waiting for it to be addressed.
@AGutan I assume the Flink update mentioned on StackOverflow didn't solve the issue? Pinging @joerg84 Now in case he hasn't tried to reproduce it yet.
@AGutan just curious did the terraform script work out of the box for you? I had to fix the IP detect script: https://github.com/joerg84/digitalocean-dcos-terraform/commit/8fc6d63e00fa1a613056c58eb7cfc100776638f5
