Github user selvinsource commented on the issue:
https://github.com/apache/zeppelin/pull/3092
Found something that could cause the issue.
in beam/pom.xml there is
```<beam.beam.version>2.0.0</beam.beam.version>```
then
```
<artifactId>beam-runners-flink_${scala.binary.version}</artifactId>```
But looking at
https://mvnrepository.com/artifact/org.apache.beam/beam-runners-flink
there isn't a beam-runners-flink_2_10 for beam version 2.0.0.
So even in Zeppelin 0.8.0 if you try to switch to scala 2.11 and run
install -DskipTests -Pbeam you will get an error but perhaps that's something
nobody ever tried (to compile beam on 2.11).
However after removing all profiles, that's the case now and a solution is
needed.
Either the beam version is updated or the beam-runners flink can be 2_10
even for scala 2.11.
@zjffdu what do you think about my analysis? Am I making sense?
