How to use it in Linux

[troublemkerrr]

hello I'm trying to use it in Ubuntu, but met some problems. I successfully compiled it, but I am confused about how to use it. I only changed the ip address in the configuration files,then I tried to run it like: ./efs-server.out namenode ./configs/NameNodeConfig.yaml ./efs-server.out datanode ./configs/DataNodeConfig.yaml then it reports an error: Error(-111): E_FILE_MKDIR Do you have any idea what might have caused this? Or can you write a more detailed documentation for linux? I would really appreciate it.
