Managing SQL Jobs

Viewing Basic Job Information on the SQL Jobs Page

The SQL Jobs page displays all SQL jobs, which may span multiple pages if there are many jobs. You can navigate to a specific page as needed. DLI allows you to view jobs in all statuses. Jobs in the job list are sorted by creation time in descending order by default.

  • IMPORT: A job that imports data to DLI
  • EXPORT: A job that exports data from DLI
  • DCL: Conventional DCLs and operations related to queue permissions
  • DDL:Conventional DDLs, including creating and deleting databases and tables
  • QUERY: A job that queries data by running SQL statements

Query

SQL statements for operations such as exporting and creating tables

You can click to copy the query statement.

Duration

Running duration of a job

Created

Time when a job is created. Jobs can be displayed in ascending or descending order of the job creation time.

Operation
  • Edit: Edit the job.
  • Cancel
    • You can terminate a job only when the job is in Submitting or Running status.
    • A job whose status is Finished, Failed, or Canceled cannot be terminated.
    • If the Cancel button is gray, you are not allowed to perform this operation.
  • Re-execute: Execute the job again.
  • SparkUI: Display the Spark job execution page.
    NOTE:
    • When you execute a job on a created queue, the cluster is restarted. It takes about 10 minutes. If you click SparkUI before the cluster is created, an empty projectID will be cached. The SparkUI page cannot be displayed. You are advised to use a dedicated queue so that the cluster will not be released. Alternatively, wait for a while after the job is submitted (the cluster is created), and then check SparkUI.
    • SparkUI can currently only display the latest 100 jobs.
  • In addition to the preceding operations, the following operations are available for QUERY jobs and asynchronous DDL jobs.
    • Submit Download Request: Download the results of asynchronous DDL and QUERY statements to a local directory. For details, see Exporting Job Results to a Local Host.
    • View Result: View the job running result.
    • Export Result: Export the job running result to the created OBS bucket.
  • In addition to the preceding operations, the EXPORT job also includes the following operations:
    • Download
  • View Log: Save job logs to the temporary OBS bucket created by DLI.
NOTE:

The View Log button is not available for synchronization jobs and jobs running on the default queue.
