I installed Sandbox(HDP 2.3.2 virtual box.ova) on Yosemite MACos and virtual box 5.0.10. It doesn't seem to come up on 127.0.01:8080 as per documentation. screen-shot-2015-12-18-at-40845-pm.png. I saw some warnings related to linux permissions while initialization of the appliance's servers. screen-shot-2015-12-18-at-40623-pm.png. Any guidance will help...
When you start the sandbox VM, it may not start on localhost. If you see the below screenshot mine is starting on 172.16.35.145. So I would need to go to 172.16.35.145:8080 to get Ambari to resolve.
If yours is saying 127.0.0.1, please try hitting 127.0.0.1 and see if the web sign in page solves at least?
Please check following things.
1) Firewall is running, if yes then stop it:- service iptables stop
and flush the rules with iptables -F command.
2) check service is running. If no then start the ambari-server servicewith command :- ambari-server start
Are you trying to access the page out of sandbox?
if yes then please check port 8080 is open and are you able to ping the machine.
I feel your your sandbox is not having on 127.0.0.0 so can you please check it first via below command
and then check ambari server status via below command
$ service ambari-server status
and if it is not running then start or restart it
$ service ambari-server start or
$ service ambari-server restart
and now you try to open ambari web ui
