Subject Re: Docker-Image for 'hello-samza'
Date Thu, 14 Jan 2016 11:07:32 GMT
The kafka error seems not to be the important piece… https://issues.apache.org/jira/browse/KAFKA-2251

I created an image that holds all services needed to rule out that somehow the job assumes
‘localhost’ connections somewhere:
https://hub.docker.com/r/qnib/samza-mono/builds/ <https://hub.docker.com/r/qnib/samza-mono/builds/>

Still get the same error. :/
