类 KerberosDelegationTokenManager

java.lang.Object

org.apache.flink.runtime.security.token.KerberosDelegationTokenManager

所有已实现的接口:

DelegationTokenManager

public class KerberosDelegationTokenManager
extends Object
implements 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 periodically logs in to the KDC with user-provided credentials, and contacts all the configured secure services to obtain delegation tokens to be distributed to the rest of the application.
