> Depending on how the web.xml gets generated, the HaServletContextListener may
> come after the UrlRewriteServletContextListener, in which case the provider
> is not available to the rewrite framework on initialization and HA
> functionality does not work.
> The web.xml config that works is:
> <listener>
>
> <listener-class>org.apache.hadoop.gateway.services.GatewayServicesContextListener</listener-class>
> </listener>
> <listener>
>
> <listener-class>org.apache.hadoop.gateway.ha.provider.HaServletContextListener</listener-class>
> </listener>
> <context-param>
> <param-name>haDescriptorLocation</param-name>
> <param-value>/WEB-INF/ha.xml</param-value>
> </context-param>
> <listener>
>
> <listener-class>org.apache.hadoop.gateway.filter.rewrite.api.UrlRewriteServletContextListener</listener-class>
> </listener>
> <context-param>
> <param-name>rewriteDescriptorLocation</param-name>
> <param-value>/WEB-INF/rewrite.xml</param-value>
> </context-param>
> but there is no guarantee in place that the web.xml will be generated as
> such.
