Hi, everyone, When I was working on this PR ( https://github.com/apache/incubator-heron/pull/3411), Josh raised up a question about the docker images supported by Heron. There are 5 images configured: centos7, debian9, ubuntu 14.04, 16.04 and 18.04.
Questions to discuss: - It could be a burden to maintain all of them. Do you feel it is necessary to support all of them? Or is there another one we should have? - For ubuntu, do we really need 3 versions? Regards, --ning
