   After turning off `security.delegation.tokens.enabled`, it is difficult for 
us to pass delegation token updates of jobmanager to taskmanager.
   
   Based on the solution in 
https://github.com/apache/flink/pull/22009#issuecomment-2122226755, I will 
follow the steps:
   
   + Implement custom `KyuubiDelegationTokenProvider` and 
`KyuubiDelegationTokenReceiver`
   + Add the following options
   
   ```
   HADOOP_PROXY_USER=proxyUser
   
security.module.factory.classes=org.apache.flink.runtime.security.modules.JaasModuleFactory,org.apache.flink.runtime.security.modules.ZookeeperModuleFactory
   security.delegation.token.provider.hadoopfs.enabled=false
   security.delegation.token.provider.s3-hadoop.enabled=false
   security.delegation.token.provider.s3-presto.enabled=false
   security.delegation.token.provider.HiveServer2.enabled=false
   security.delegation.token.provider.hbase.enabled=false
   ```
