Configuring HTTP Cookie Persistence

Reference material for enabling HTTP cookie persistence when setting up Kerberos for non-Ambari clusters.

During HTTP authentication, a cookie is dropped. This is a persistent cookie that is valid across browser sessions. For clusters that require enhanced security, it is desirable to have a session cookie that gets deleted when the user closes the browser session.

You can use the following core-site.xml property to specify cookie persistence across browser sessions.

<property>
   <name>hadoop.http.authentication.cookie.persistent</name>
   <value>true</value> 
</property>

The default value for this property is false.
