Kobi Salant commented on BEAM-981:
----------------------------------
The error shown in the description is caused by conflicting netty dependencies
between spark and beam-sdks-java-io-google-cloud-platform module.
io.netty.util.ReferenceCounted is included in netty-all version 4.0.29.final
from spark dependency.
The same class is also brought by beam-sdks-java-io-google-cloud-platform from
its grpc-netty dependency, this time from netty-common version 4.1.8.final.
The two classes have different abstract methods and
org.apache.spark.network.protocol.MessageWithHeader implements only the
4.0.29.final version.
I have created a PR https://github.com/apache/beam/pull/2997 not to handle the
conflict which is simply a matter of fixing the application's dependencies but
to add the ability to pass jars via the SparkPipelineOptions to SparkConf so
all the needed classes will be available to the application.
I have tested this on the archetype using the shaded packaged jar on a remote
cluster

> It looks like a conflict between the Netty version used in Spark and the one
> in Beam (just guessing).
> The workaround is to use {{spark-submit}}.
