Jared Stehler commented on FLINK-8265:
--------------------------------------
There is a shaded jackson class with jackson2 in the package, but none with the
path shown. It seems like there is a missing include for jackson here in the
flink-mesos pom?
{code}
<artifactSet>
<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>
<relocations
combine.children="append">
<relocation>
<pattern>com.google.protobuf</pattern>
<shadedPattern>org.apache.flink.mesos.shaded.com.google.protobuf</shadedPattern>
</relocation>
<relocation>
<pattern>com.fasterxml.jackson</pattern>
<shadedPattern>org.apache.flink.mesos.shaded.com.fasterxml.jackson</shadedPattern>
</relocation>
</relocations>
{code}
I was able as a workaround to build a simple shaded jackson deps jar relocated
to "org.apache.flink.mesos.shaded.com.fasterxml.jackson" and adding that to my
/lib.
