Hi Aljoscha, we are running Flink in Stand alone mode, inside Docker in AWS. I will check tomorrow the dependencies, although i'm wondering: I'm running Flink 1.3 averywhere and the appropiate ES connector which was only released with 1.3, so it's weird where this dependency mix up comes from ... let's see ...
