> When making a requests through knox to WebHDFS HA the following scenario does not work. 
> WebHDFS HA is setup with two nodes, one active and one in standby. WebHDFS HA is configured in knox with these two urls.
> The active namenode is restarted (comes back up as standby node) and a request is made. A failover happens and the request is successful. 
> The new active node is then restarted so that the old active node is now active again. When another request is made the request hangs.
> Please note that this scenario is only true in a secure cluster setup.
