There are some overlaps between YARN UI2, and Application Catalog. The same deployment feature exists in YARN UI2 and Application Catalog. It would be nice to present the application catalog as the first view to end user to speed up deployment of application. UI2 is a monitoring and resource allocation and prioritization UI. It might be more user friendly to transfer UI2 deployment feature into Application Catalog to improve usability for both end user who launches the apps, and system administrator who monitors the apps usage.
