-----------------------------------------
This patch prevents a 2.8.0 client submitting work to a secure Hadoop 2.6/2.7
cluster.

>
> During http authentication, a cookie which contains the authentication token
> is dropped. The expiry time of the authentication token can be configured via
> hadoop.http.authentication.token.validity. The default value is 10 hours.
> For clusters which require enhanced security, it is desirable to have a
> configurable MaxInActiveInterval for the authentication token. If there is no
> activity during MaxInActiveInterval, the authentication token will be
> invalidated.
> The MaxInActiveInterval will be less than
> hadoop.http.authentication.token.validity. The default value will be 30
> minutes.
