Authorizing Access to a Big Data Asset

The Elasticsearch big data type is used as an example to describe how to authorize access to big data assets. To authorize access to other types of big data assets, click the corresponding big data type.

1. Log in to the management console.
2. Click in the upper left corner and select a region or project.
3. In the navigation tree on the left, click . Choose Security & Compliance > Data Security Center .
4. In the navigation tree on the left, choose Asset Management > Asset Center. The Asset Center page is displayed.
5. Click Elasticsearch and choose the ElasticSearch Instance tab.
6. Click Elasticsearch instance. The Elasticsearch instance tab page is displayed. Authorization can be performed in either of the following ways:
   • Method 1: Click Authorize in the Operation column of the ElasticSearch instance list, and enter the Elasticsearch index information to perform authorization.
   • Method 2: Click an instance name to go to the instance details page and view the status of all indexes of the instance.

     Then click Authorize in the Operation column to authorize unauthorized indexes.

     NOTE:

     Click Set as Default. The metadata task creates a connection with the default database and draws the metadata of the instance.

7. Click the Index tab to view the connection status of authorized assets.
   After the asset authorization is complete, the Connectivity of the asset is Checking, which means DSC is checking the database connectivity.

   • If DSC can access the added asset, the Connectivity is Succeeded.
   • If the DSC cannot access the added asset, the Connectivity is Failed. Move the cursor to Failed to view the failure cause or rectify the fault by referring to section How Do I Troubleshoot the Failure in Connecting to the Added Database?

• 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 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.
  • For details about the big data types that support metadata collection, see section Creating a Metadata Collection Task.
  • You can refer to section Creating a Metadata Collection Task to manually create a metadata collection task.
• Creating an identification task

  On the Databases tab page, click Create Identification Task in the Operation column of the asset list to create an identification task for an asset. For details, see section Creating an Identification Task.
