@Internal
public interface DelegationTokenManager

Manager for delegation tokens in a Flink cluster.

When delegation token renewal is enabled, this manager will make sure long-running apps can run without interruption while accessing secured services. It must contact all the configured secure services to obtain delegation tokens to be distributed to the rest of the application.
