Constructor Detail

AuthenticationTokenKeyManager

public AuthenticationTokenKeyManager(AuthenticationTokenSecretManager mgr,
                                     ZooAuthenticationKeyDistributor dist,
                                     long keyUpdateInterval,
                                     long tokenMaxLifetime)

Parameters:

mgr - The SecretManager in use

dist - The implementation to distribute AuthenticationKeys to ZooKeeper

keyUpdateInterval - The frequency, in milliseconds, that new AuthenticationKeys are created

tokenMaxLifetime - The lifetime, in milliseconds, of generated AuthenticationKeys (and subsequently delegation tokens).
