Use semicolons (;) to separate the IP addresses.

OBS storage support

Whether to support OBS storage. If the Hudi table data is stored in OBS, you need to enable this function.

Yes

AK

This parameter is available when OBS storage support is set to Yes.

AK and SK are used to log in to the OBS server.

You need to create an access key for the current account and obtain an AK/SK pair.

To obtain an access key, perform the following steps:
  1. Log in to the management console, move the cursor to the username in the upper right corner, and select My Credentials from the drop-down list.
  2. On the My Credentials page, choose Access Keys, and click Create Access Key. See Figure 1.
    Figure 1 Clicking Create Access Key
  3. Click OK and save the access key file as prompted. The access key file will be saved to your browser's configured download location. Open the credentials.csv file to view Access Key Id and Secret Access Key.
    NOTE:
    • Only two access keys can be added for each user.
    • To ensure access key security, the access key is automatically downloaded only when it is generated for the first time and cannot be obtained from the management console later. Keep them properly.

SK

OBS Test Path

This parameter is available when OBS storage support is set to Yes.

Enter a complete file path. The permission to access the path will be verified through the metadata query API.

NOTE:
  • For object storage, the path must be accurate to object, for example, obs://bucket/dir/test.txt. Otherwise, a 404 error occurs.
  • For a parallel file system, the path must be accurate to directory, for example, obs://bucket/dir.

obs://bucket/dir/test.txt

Hive Properties
