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}.

    if (!credentials.getInstanceId().equals(HdfsZooInstance.getInstance().getInstanceID()))
      throw new ThriftSecurityException(credentials.getPrincipal(), SecurityErrorCode.INVALID_INSTANCEID);


    Credentials creds = Credentials.fromThrift(credentials);
    if (isSystemUser(credentials)) {
      if (!(SystemCredentials.get().equals(creds))) {
        throw new ThriftSecurityException(creds.getPrincipal(), SecurityErrorCode.BAD_CREDENTIALS);
      }
