Jared, I think you're correct that the shaded `ObjectMapper` is missing. Based on the above details and a quick look at the Fenzo code, it appears that this bug is expressed when you've configured some hard constraints that Mesos couldn't satisfy. Do you agree? Thanks also for suggesting a fix, would you mind annotating FLINK-8265?
https://issues.apache.org/jira/browse/FLINK-8265 Sorry about this!
