Yusaku Sako commented on AMBARI-5150:
-------------------------------------

[~xiwang0309]
I applied the patch and App.version (client) and server version via the API were different, but I do not get the error message and get the login page.
This should appear on page load, before login page is displayed.
For example, I can go ahead and create a cluster even if the server/client versions do not match.

> Under some situations, the browser cache isn't cleared and after doing upgrade, you have "older UI working against newer server", which can cause all sorts of problems.
> So, show an alert message(Server / Web client version mismatch ) before Ambari web loaded.
