Currently one has to give an jdbc:hive2 url in order for Beeline to connect a hiveserver2 instance. It would be great if Beeline can get the info somehow (from a properties file at a well-known location?) and connect automatically if user doesn't specify such a url. If the properties file is not present, then beeline would expect user to provide the url and credentials using !connect or ./beeline -u .. commands
While Beeline is flexible (being a mere JDBC client), most environments would have just a single HS2. Having users to manually connect into this via either "beeline ~/.propsfile" or -u or !connect statements is lowering the experience part.
