Possibly missing an include for jackson here in the flink-mesos pom?

<includes combine.children="append">

<include>com.google.protobuf:protobuf-java</include>

<include>org.apache.mesos:mesos</include>

<include>com.netflix.fenzo:fenzo-core</include>

</includes>

</artifactSet>

<pattern>com.google.protobuf</pattern>

<shadedPattern>org.apache.flink.mesos.shaded.com.google.protobuf</shadedPattern>

</relocation>

<pattern>com.fasterxml.jackson</pattern>

<shadedPattern>org.apache.flink.mesos.shaded.com.fasterxml.jackson</shadedPattern>

</relocation>

</relocations>

I see a shaded jackson class with jackson2 in the package, but none with the path shown below.
