@cnauroth @slfan1989 Thanks for the feedback. Not sure if we should keep
discussing here or under a new JIRA ticket but here are few thoughts.
The fact that the built-in config files such as `core-default.xml` use
deprecated properties seems problematic to me. I would argue that once a
property is deprecated it shouldn't be used anywhere inside the project. If we
agree on this then maybe we should invest some time to remove/replace existing
usages of deprecated properties such as `fs.default.name`.
Moreover, the deprecation warnings can be disabled (or directed to another
file) by end-users by changing the respective logging configuration. I am
wondering if it is normal/expected to have all logs directed in the console for
CLI utilities.
