Hi Lewis, Sorry to hear that you're having trouble running the wordcount example with Celeborn.
Based on the information you shared, I would suggest you run MapReduce with Celeborn on a Hadoop cluster instead of pseudo-disturb mode. Celeborn client in MapReduce needs to write a config file into the Hadoop file system. If that doesn't resolve the issue, please let me know and I'll be happy to help you troubleshoot further. Celeborn has a Slack workspace if you are convenient to join.
