  • Deleting an instance

    A big data instance can be deleted only when the big data instance is a self-built instance and the number of authorized databases or indexes in it is 0.

    Select multiple self-built instances and click Batch Delete in the upper left corner of the instance list to delete the instances. You can also click Delete in the Operation column of the instance list to delete a single instance.

  • Drawing metadata of an instance
    • If the number of authorized databases in the MRS_Hive instance is greater than 0, click More > Refresh in the Operation column of the Hive instance list to automatically create a metadata task to obtain the database, table, and column information of the instance.
    • If you enable the function of automatically creating a metadata task when adding a Hive instance, the system automatically creates a metadata task to obtain all metadata of the instance after the instance is created.
    • You can manually create a metadata task by referring to section Step 1: Scanning Metadata.
  • Creating an identification task

    In the Databases tab, locate the target asset and click Create Identification Task in the Operation column. For details, see Creating an Identification Task.
