Flink Web UI Permission Management

To access and use the Flink web UI to perform service operations, you need to assign FlinkServer-related permissions to users. User admin on FusionInsight Manager does not have FlinkServer service operation permissions.

Applications (tenants) in FlinkServer are the maximum management scope, including cluster connection management, data connection management, application management, stream table management, and job management.

There are three types of resource permissions for FlinkServer, as shown in Table 1.
