Review comment:
       I designed to configure the Fkink permission authentication to the 
cluster level. Our Flink cluster has already configured Kerberos, so we only 
need to configure the Meta Client Principal of Hive to connect.If Kerberos 
permission authentication is not configured for the Flink cluster, 
authentication must be performed at the Task level.
