Description
Currently when Ambari is built using maven (without -DnewVersion="1.3.0" param), the server version defaults to '1.3.0' and the UI defaults to ''. Due to this the UI becomes incompatible with server (image attached) - even though both were built at the same time.
If -DnewVersion="1.3.0" is specified, it should be used for both server and UI. If not specified, both should default to the same version.
