Allen Wittenauer commented on YARN-4478:
----------------------------------------
You realize that RFC is talking about DNS and not /etc/hosts, right? It's
specifically to prevent the DNS resolver from adding more domains during
resolution.
Also, in 20+ years of Unix system administration, I have never configured
/etc/hosts with an ending period. That's because /etc/hosts resolution isn't
supposed to go through the DNS resolver at all.
