Search before asking

  • I have searched in the issues and found no similar issues.

Describe the bug

Building a docker image via deploy/kubernetes/docker/build.sh --hadoop-version 3.2.4 and using that with Netty and Epoll fails because the image contains the Hadoop binaries, which contain a different netty-all jar then the RSS shuffle server.

This can be fixed by

  • either not include the Hadoop binaries in the Docker image
  • or by downgrading Netty version to match the version contained in the Hadoop binaries

Affects Version(s)
