Managing Flink Job Permissions¶
Scenario¶
You can isolate Flink jobs allocated to different users by setting permissions to ensure data query performance.
The administrator and job creator have all permissions, which cannot be set or modified by other users.
Flink Job Permission Operations¶
On the left of the DLI management console, choose Job Management > Flink Jobs.
Select the job to be configured and choose More > Permissions in the Operation column. The User Permissions area displays the list of users who have permissions on the job.
You can assign queue permissions to new users, modify permissions for users who have some permissions of a queue, and revoke all permissions of a user on a queue.
Assign permissions to a new user.
A new user does not have permissions on the job.
Click Grant Permission on the right of User Permissions page. The Grant Permission dialog box is displayed.
Specify Username and select corresponding permissions.
Click OK.
Table 1 describes the related parameters.

In the displayed Set Permission dialog box, modify the permissions of the current user. Table 1 lists the detailed permission descriptions.

Click OK.
To revoke all permissions of a user on a job, perform the following steps:
In the list under User Permissions for a job, locate the user whose permissions need to be revoked, click Revoke Permission in the Operation column, and click Yes. After this operation, the user does not have any permission on the job.
Flink Job Permissions¶
View Job Details
Tenants and the admin user can view and operate all jobs.
Subusers and users with the read-only permission can only view their own jobs.
Note
If another user grants any permission other than the job viewing permission to a subuser, the job is displayed in the job list, but the details cannot be viewed by the subuser.
Start Job
To use a dedicated queue, you must have the permission to submit and start jobs.
To use a shared queue, you only need to have the permission to start jobs.
Stop Job
To use a dedicated queue, you must have the permission to stop jobs and queues.
To use a shared queue, you only need to have the permission to stop jobs.
Delete Job
If a job can be deleted, you can delete the job if you were granted this permission.
If a job cannot be deleted, the system stops the job before you delete it. For details about how to stop a job, see Stop Job. In addition, you must have the permission to delete the job.
Create Job
By default, sub-users cannot create jobs.
To create a job, you must have this permission. Currently, only the admin user has the permission to create jobs. In addition, the user must have the permission of the related package group or package used by the job.
Modify Job
When modifying a job, you need to have the permission to update the job and the permission to the package group or package used by the job belongs.
