    @aljoscha Sorry for replying late, your suggestion sounds good to me. In fact, I was hesitating to add `getDefaultParallelism()` in `ContextEnvironment` and `ClusterClient` for there have been `getParallelism()` in `ContextEnvironment`. Thank you for your suggestion, I will fix it as you suggested soon :)

> In the constructor of {{StreamContextEnvironment}} we read the {{DEFAULT_PARALLELISM}} from the {{GlobalConfiguration}}. This assumes that the environment variables are correctly set and can lead to problems. We should read the default parallelism in the client and set it in the {{ContextEnvironment}} that it creates. This can then be read by the {{StreamContextEnvironment}}.
