SQL Job Management

SQL jobs allow you to execute SQL statements entered in the SQL job editing window, import data, and export data.

SQL job management provides the following functions:

Searching for Jobs: Search for jobs that meet the search criteria.
Viewing Job Details: Display job details.
Terminating a Job: Stop a job in the Submitting or Running status.
Exporting Query Results: A maximum of 1000 records can be displayed in the query result on the console. To view more or all data, you can export the data to OBS.

SQL Jobs page

On the Overview page of the DLI console, click SQL Jobs to go to the SQL job management page. Alternatively, you can click Job Management > SQL Jobs. The job list displays all SQL jobs. If there are a large number of jobs, they will be displayed on multiple pages. You can switch to the specified page as needed. DLI allows you to view jobs in all statuses. By default, jobs in the job list are displayed in descending order of the job creation time.

**Table 1** SQL Job management parameters
Parameter	Description
Queues	Name of the queue to which a job belongs
Username	Name of the user who executed the job.
Type	Job type. The following types are supported: 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 querys data by running SQL statements INSERT: A job that inserts data by running SQL statements UPDATE: A job that updates data. DELETE: A job that deletes a SQL job. DATA_MIGRATION: A job that migrates data. RESTART_QUEUE: A job that restarts a queue. SCALE_QUEUE: A job that changes queue specifications, including sale-out and scale-in.
Status	Job status. Possible values are as follows: Submitting Running Finished Canceled Failed Scaling
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. Currently, only the latest 100 job information records are displayed on the SparkUI of DLI. In addition to the preceding operations, the following operations are available for QUERY jobs and asynchronous DDL jobs. View Result: View the job running result. Export Result: Export the job running result to the created OBS bucket. For details, see section Exporting Query Results. 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. Export Log: Export logs to the created OBS bucket. If the job is in the Running state, logs cannot be exported. NOTE: To export the logs, you need to obtain the permission to create an OBS bucket. Log archiving and export are not available for synchronization jobs and jobs running on the default queue.
