All Implemented Interfaces:

public class EsTokenIdentifier
extends AbstractDelegationTokenIdentifier

The Hadoop Token Identifier for any generic token that contains an EsToken within it.

Hadoop tokens are generic byte holders that can hold any kind of auth information within them. To identify what specific auth information is within them, they require an "Identifier" to be provided at creation time. This class is used as that identifier.

Also included in this class is the Hadoop defined token renewer interface which allows for any process that contains the appropriate service loader info to renew and cancel an existing token.

Service loader information is at META-INF/services/org.apache.hadoop.security.token.TokenRenewer and META-INF/services/org.apache.hadoop.security.token.TokenIdentifier
