I am a beginner and following the Learning the Ropes tutorial and am unable to connect to the welcome screen. I have spent a few days trying different hosts file modifications and different browser address and none seem to work. I have also tried all these on a PC and Mac trying both VMware and VirtualBox. I have stuck with VirtualBox because it seem like the one people are most using in the forum questions. Can anyone please provide an actual step by step? Things I have tried: host file - 127.0.0.1 localhost sandbox.hortonworks.com vs 127.0.0.1 sandbox.hotronworks.com vs 192.168.XX.XX localhost sandbox.hortonworks.com browser ips: 127.0.01.1:8888 vs localhost:8888 vs 192.168.XX.XX:8888 Firewall is NOT enabled Also there are three choices when I start the VirtualBox CentOs Linux (4.12.4-1.elrepo.x86_64) 7 (Core) - this generates a blank screen CentOS Linux (3.10.0-514.26.2.el7.x86_64) 7 (Core) - this generates a blank screen CentOS Linux (0-rescue-6f5d5e9d826b4471ad0elf7a92e697dd) 7 (Core) - this works and brings up the screen seen in the tutorial Can someone explain this? Sorry I am a true beginner. ... View more
