I figured out the problem: It is a wrong protobuf-java version.
`flink-runtime` depends on `akka-remote_2.10:2.3.7` which depends on
`protobuf-java:2.5.0`. However, in the Zeppelin parent pom the `protobuf-java`
version is manually set to `2.4.1`. There is a comment which declares this as a
work-around to make Zeppelin build with Hadoop/YARN 2.2.
As a quick work-around you can set the protobuf-java version to 2.5.0 in
the zeppelin-flink `pom.xml`. I'll also open a JIRA to shade the protobuf and
akka dependency away in the flink project. This should solve this issue
permanently.
