Github user aljoscha commented on the issue: https://github.com/apache/flink/pull/5208 With this change we will have Jackson shaded/relocated twice in `flink-dist`: once under `org.apacha.flink.shaded.jackson2` and once under `org.apache.flink.mesos.shaded`. @zentol Wouldn't it suffice to change the shading pattern in `flink-mesos` to `org.apache.flink.shaded.jackson2.com.fasterxml.jackson` so that the Fenzo code is correctly changed to refer to our (already) shaded/relocated Jackson?
