                           | The domain to use for the HTTP cookie that stores 
the authentication token. For authentication to work correctly across all nodes 
in the cluster the domain must be correctly set. There is no default value, the 
HTTP cookie will not have a domain working only with the hostname issuing the 
HTTP cookie.                                                  |
 | `hadoop.http.authentication.cookie.persistent`         | `false` (session 
cookie)                       | Specifies the persistence of the HTTP cookie. 
If the value is true, the cookie is a persistent one. Otherwise, it is a 
session cookie. *IMPORTANT*: when using IP addresses, browsers ignore cookies 
with domain settings. For this setting to work properly all nodes in the 
cluster must be configured to generate URLs with `hostname.domain` names on it.
