Description

While installing Metron services, the "Assign Masters" page does a validation for co-location of some of the components. There is also a "warning" message for one of the components viz. Metron Parsers which alerts the user to install Storm supervisor in the subsequent "Assign Slaves and Clients" screen.

When user proceeds from this page, there is a warning dialog about "Validation Issues" prompting the user to either click Continue Anyway or Cancel. See attached screenshot

Upon clicking "Cancel", the installer UI hangs with the Next button grayed out and the moue pointer spinning See attached screenshot .

The only option is to reload the installer page by refreshing the browser.

Note that the installer works fine when the Continue Anyway button is clicked.
