# Edit configuration files for users Your cluster administrator must download configuration files from the cluster for the applications your teams are using, and then edit them to include Pentaho-specific and user-specific parameters. These modified files must be provided to the users and must be copied to the user's directory: `/.pentaho/metastore/pentaho/NamedCluster/Configs/`. When the user creates a named connection, this `` directory is created. When the user sets up the named connection, PDI copies these configuration files into that directory. The cluster administrator must provide the user with the name to assign the named connection, so that PDI can copy these modified files into that directory. See the **Pentaho Data Integration** document for details about named connections. The following files must be provided to your users: * `core-site.xml` * `mapred-site.xml` * `hdfs-site.xml` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.pentaho.com/install/9.3-install/pentaho-configuration/tasks-to-be-performed-by-an-it-administrator/set-up-the-pentaho-server-to-connect-to-a-hadoop-cluster/additional-configurations-for-specific-distributions-connecting-to-a-cluster/advanced-settings-for-connecting-to-a-amazon-emr-cluster/edit-configuration-files-for-users-emr.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
