Hi Chenghao, Apache Hop supports HDFS over VFS[1]. However, there may be some system configuration that is required. Are you able to view and access your hdfs files over CLI tools e.g. `hdfs dfs ls <YOUR_PATH>`? Are there any logs in the Hop Gui output (console or your pipeline) when you try to access files of HDFS?
