Creating an SMN Topic

Scenario

Once you have created an SMN topic, you can easily subscribe to it by going to the Topic Management > Topics page of the SMN console. You can choose to receive notifications via SMS or email. After the subscription is successful, if a job fails, the system automatically sends a message to the subscription endpoint you specified.

  • If a job fails within 1 minute of submission, a message notification is not triggered.
  • If a job fails after 1 minute of submission, the system automatically sends a message to the subscriber terminal you specified.

Procedure

  1. Log in to the DLI management console.
  2. In the navigation pane, choose Resources > Queue Management. Click Create SMN Topic in the upper left corner of the displayed page. The Create SMN Topic dialog box appears.

  3. Select a queue and click OK.
    • You can select a single queue or all queues.
    • If you create a topic for a queue and another topic for all queues, the SMN of all queues does not include the message of the single queue.
    • After a message notification topic is created, you will receive a message notification only when a Spark job created on the subscription queue fails.
