Optional: HTTP Cookie Persistence

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.

In HDP-2.3.4 and higher versions, you can use the following property in the etc/hadoop/conf/core-site.xml file to specify cookie persistence across browser sessions.


The default value for this property is false.
