You can register the shared directory and HDFS directory in iServer, and use the CSV files, index files, UDB dataset files, and subfolders in the directory for distributed analysis services.

IServer machine learning services provide processing and analysis capabilities for UDB datasets. At this point, you can register the shared directory in iServer, and the udb dataset files and subfolders in the directory are used for machine learning services. Below, we will provide you with a detailed introduction.
