Ismaël Mejía commented on BEAM-3098:
------------------------------------
Actually the issue is that grpc is leaking netty on all the runners and this
has conflicts with Spark at runtime because they use netty 4.0 by default
instead of 4.1, This is the case of BEAM-3519
I saw your PR for that, but I have the impression that both issues are
intertwined, because using the shaded version of gRPC would require to upgrade
it, no?
> Upgrade Java grpc version

> Beam Java currently depends on grpc 1.2, which was released in March. It
> would be great if the dependency could be update to something newer, like
> grpc 1.7.0
