    Dataphin:Initialize the metadata warehouse using Lindorm (compute engine)

    Last Updated:Jan 21, 2026

    The Dataphin metadata warehouse centrally manages business and compute engine metadata. It is a Dataphin project within the metadata warehouse tenant (OPS tenant) and consists of periodic data integration nodes, SQL script nodes, and Shell nodes. Initializing the metadata warehouse involves configuring the compute engine type for Dataphin and initializing its metadata. This topic describes how to initialize the metadata warehouse using Lindorm (compute engine).

    Prerequisites

    Before you initialize the metadata warehouse with Lindorm (compute engine), you must activate its compute engine and file engine. For more information, see Engine types.

    Permissions

    Only accounts with the super administrator role for the metadata warehouse tenant or the system administrator role can initialize the system.

    Important

    Keep the account and password for the super administrator of the metadata warehouse tenant or the system administrator secure. When you are logged on as the super administrator of the metadata warehouse tenant, proceed with caution.

    Procedure

    1. On the Dataphin home page, from the top menu bar, choose Management Center > System Settings.

    2. In the navigation pane on the left, choose System O&M > Metadata Warehouse Settings. On the Metadata Warehouse Settings page, click Start.

    3. In the Select Initialization Engine Type step, select Lindorm (compute engine) as the engine type.

      Important

      If the metadata warehouse is already initialized, the engine that was last used for a successful initialization is selected by default. If you switch to an incompatible compute engine, the administration features become unavailable.

    4. Click Next.

    5. On the Parameter Settings page, configure the parameters for the Lindorm (compute engine).

      Parameter

      Description

      core-site.xml

      Upload the core-site.xml, hdfs-site.xml, and hive-site.xml configuration files for Lindorm (compute engine). For more information about the configuration files, see Connect to an instance.

      hdfs-site.xml

      hive-site.xml

      database

      Enter the database name for the Lindorm (compute engine).

      JDBC URL

      Configure the JDBC URL for Lindorm (compute engine). To obtain the endpoint, see View endpoints.

      Metadata production project

      The logical project for metadata production and processing. The recommended name is dataphin_meta. Keep this name unchanged when you re-initialize. Otherwise, the initialization fails.

    6. Click Test Connection. After the connection test is successful, click Next.

    7. On the initialization page, click Start.

      Note

      The initialization process takes about 15 minutes.

    8. When a success message appears, click Finish to complete the configuration.

    What to do next

    After you initialize the system metadata, set the compute engine for the Dataphin instance. When the metadata warehouse engine is set to Lindorm (compute engine), the business tenant engine can be set to any type of engine except MaxCompute. For more information about how to set the engine, see Compute Settings.
