The class is there; this issue is a static initializer error, probably from
other missing classes. I’ll try using the uber jar to see if that helps any,
and will report back.
I’ve included the shaded jar as a maven dependency:
<dependency>
<groupId>org.apache.flink</groupId>
<artifactId>flink-shaded-hadoop2</artifactId>
<version>${flink.version}</version>
</dependency>
