Why Is Error Message "Authentication failed" Displayed During Flink Jar Job Running?

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

Service authorization is not configured for the account on the Global Configuration page. When the account is used to create a datasource connection to access external data, the access fails.

Solution

  2. On the Service Authorization page, select all agency permissions.
