Creating a FlinkServer Role

Create and configure a FlinkServer role on Manager as an MRS cluster administrator. A FlinkServer role can be configured with the FlinkServer administrator permission and the permissions to edit and view applications.

You need to set permissions for the specified user in FlinkServer so that they can update, query, and delete data.

Prerequisites

The cluster administrator has planned permissions based on service requirements.

Procedure

  1. Log in to Manager.
  2. Choose System > Permission > Role.
  3. On the displayed page, click Create Role and specify Role Name and Description.
  4. Set Configure Resource Permission.

    FlinkServer permissions are as follows:

    • FlinkServer Admin Privilege: highest-level permission. Users with the permission can perform service operations on all FlinkServer applications.
    • FlinkServer Application: Users can set application view and applications management permissions on applications.
