Ismaël Mejía commented on BEAM-3668:
------------------------------------
This is not a problem of the spark runner, this is an issue of GCP IO leaking
netty into the classpath and producing a conflict with the spark runner. See
BEAM-3519. I just PRed a workaround for the archetype/quickstart, but I am
wondering if the unattended consequence is that the Spark runner make have some
issues with GCP IO for this release.
