This is just getting more and more interesting. I never thought of -hiveconf option, and always assumed it was a typo of --hiveconf. (That's why I edited the one, which triggered the discovery.) I just checked and found that both work, which is out of my surprise.
With this assumption, Beeline has implemented only --hiveconf to mimic CLI. As to the documentation, I think we can stick to --hiveconf from now on, since they are supported by both CLI and Beeline. However, -hiveconf will continue to work for CLI until its death.
