Symptom

An exception occurred when a Flink Jar job is running. The following error information is displayed in the job log: 
org.apache.flink.shaded.curator.org.apache.curator.ConnectionState - Authentication failed

Possible Causes

Solution

  2. On the agency settings page, select required permissions.

    DLI Datasource Connections Agency Access is the permissions to access and use VPCs, subnets, routes, and VPC peering connections in datasource scenarios.

    For more information, see DLI Agency Permissions.

  3. Select the permissions to be included in dli_management_agency and click Update.
