When i run 127.0.0.1:8888 on my browser, and press launch dashboard, instead of going to the dashboard i get the below image

I am not able to get to the dashboard to access hadoop features in my hdb sandbox. Can anyone help me ?

1. Are you sure that your Sandbox instance started successfully? Do you see the welcome screen of the sandbox in the VirtualBox/VMWare UI ?

2. Have you allocated 8 GB or more RAM to your Sandbox instance?

3. Are you able to do SSH to your HDP Sandbox instance where Ambari Server is running and able to verify if the port 8080 is opened?

# ssh root@127.0.0.1  -p 2222
Enter Password: hadoop

# netstat -tnlpa | grep 8080
# ambari-server status
# ambari-server restart

.

Additionally please refer to the following doc to verify if you missed any step? https://hortonworks.com/tutorial/learning-the-ropes-of-the-hortonworks-sandbox/

I have the same problem. My host is Ubuntu 18.04, VM Virtual Box

I tried both from the comamnd line

ssh root@sandbox-hdp.hortonworks.com -p 4200
ssh: Could not resolve hostname sandbox-hdp.hortonworks.com: Name or service not known

Although I added the line to /etc/hosts

{127.0.0.1} sandbox-hdp.hortonworks.com sandbox-hdf.hortonworks.com

If I go for VM

Next step is to launch a dashboard on 1080

What should I try now? My network adapter is attached to NAT. I already checked the port settings.

If I go to Advanced HDP and then choose Zepellin

502 Bad Gateway
nginx/1.15.7


How to fix this?
