I am having a very similar problem with cassandra-driver-core 3.0.0 and Google
Dataflow. Deploying to Dataflow sometimes works, sometimes gives the netty
exception:
{code:java}

{code}
Is there a known workaround for now?

I've uploaded two patches: one contains changes only to build.xml (in case
you'd like to make sure that binaries are correct yourself) and the same exact
patch only with binaries I've downloaded from netty maven repository.
FWIW, even splitting won't solve the issue since Cassandra does depend on
`common`, even if it wouldn't depend directly it would still depend on `buffer`
which depends on `common`.

> {{PlatformDependent}} comes from netty-common, of which version 4.0.33 is on
> the classpath, but it's also provided by netty-all, which has version 4.0.23
> brought in by cassandra. By a fluke of classpath ordering, the classloader
> has loaded the netty buffer classes from netty-buffer 4.0.33, but the
> PlatformDependent class from netty-all 4.0.23, and these two versions are not
> binary compatible, hence the linkage error.
> Essentially to avoid these problems in serious projects, anyone that ever
> brings in cassandra is going to have to exclude the netty dependency from it,
> which is error prone, and when you get it wrong, due to the nature of
> classpath ordering bugs, it might not be till you deploy to production that
> you actually find out there's a problem.
