> I load the UI in my browser and traverse to all the tabs. Then I disconnect
> the network. The tabs "Queues", "Applications" and "Nodes" continue to work
> even when there is no network connection. However, the "Cluster Overview" tab
> does not work and UI shows "Sorry, Error Occurred.". This tab should also
> continue to show the already loaded models, for better usability.
> We should also add a small message on the top of the UI when the network
> connection is gone. It is very similar to what gmail or other modern
> applications do today. An exception of type
> {color:red}net::ERR_INTERNET_DISCONNECTED{color} is already thrown, which can
> be caught and this small message can be marked visible.
