Managing Loader Links

Updated at: Nov 06, 2019 GMT+08:00


You can create, view, edit, and delete links on the Loader page.


You have accessed the Loader page. For details, see Loader Page.

Creating a Link

  1. On the Loader page, click Manage links.
  2. Click New link and configure link parameters.

    For details about the parameters, see Loader Link Configuration.

  3. Click Save.

    If link configurations, for example, IP address, port, and access user information, are incorrect, the link will fail to be verified and saved. In addition, VPC configurations may affect the network connectivity.

    You can click Test to immediately check whether the link is available.

Viewing a Link

  1. On the Loader page, click Manage links.

    • If Kerberos authentication is enabled in the cluster, all links created by the current user are displayed by default and other users' links cannot be displayed.
    • If Kerberos authentication is disabled in the cluster, all Loader links of the cluster are displayed.

  2. In the search box of the Sqoop Links, enter a link name to filter the link.

Editing a Link

  1. On the Loader page, click Manage links.
  2. Click the link name to go to the edit page.
  3. Modify the link configuration parameters based on service requirements.
  4. Click Test.

    If the test is successful, go to 5. If OBS Server fails to be connected, repeat 3.

  5. Click Save.

    If a Loader job has integrated into a Loader link, editing the link parameters may affect Loader running.

Deleting a Link

  1. On the Loader page, click Manage links.
  2. In the line of the link, click Delete.
  3. In the dialog box, click Yes, delete it.

    If a Loader job has been integrated into a Loader link, the deletion of the Loader link is not allowed.
