org.apache.accumulo.core.security.Credentials
A wrapper for internal use. This class carries the instance, principal, and authentication token for use in the public API, in a non-serialized form. This is important, so that the authentication token carried in a {@link Connector} can be destroyed, invalidating future RPC operations from that {@link Connector}.
