Github user tillrohrmann commented on the issue: https://github.com/apache/flink/pull/2177 I think it's a good idea to merge `container` and `containerized`. I think the idea is to introduce some general container parameters, such as the `heap-cutoff-ratio`, which are valid not only for yarn but also for mesos. Therefore, the `container/containered/containerized` prefix was introduced. Given that we don't have mesos support yet it might be confusing. However, changing the parameter names too often, given that they are declared public evolving, will cause pain for users. Which duplicate configuration parameters are you referring to @StephanEwen?
