@Asier Gomez - Do you mean disable the firewall on your local machine/computer or is there a firewall included in the Sandbox?

@jwhitmore solved this problem with his detailed advice on this post: https://community.hortonworks.com/questions/79042/step-12-not-showing-welcome-page-as-mentioned.html

Tips for others reading the above instructions: 1. For step 2, it's important you execute 'ssh -p 2222 root@localhost' AFTER ssh'g into your SANDBOX as root. In other words, locahost is relative to your sandbox. I saw similar advice on other posts but the excerpt above made it obvious. Thank you @jwhitmore for so much detail! 2. The system prompts you for the default password ('hadoop') twice, first when you ssh over port 2222 to local host ('root@localhost's password' in excerpt above) and again after the admonition to change your password ('(current) UNIX password:). Only then do you enter your NEW password. That confused me the first time round.

Thanks @Edgar Orendain ... I read those port-forwarding instructions too literally. Modified my ~./ssh/config using the username I created when I set up my Sandbox and was able to ssh in using the port-forwarding alias, however I still get ‘command not found’ when running ‘ambari-admin-password-reset’ as root. After setting up port-forwarding, literally typing ‘http://localhost:8888' got me to the splash screen. When I clicked on ‘Launch Dashboard’ I got a log on screen and tried ever username/password combination I could think of. No luck. Also when I try ‘http://localhost:8080’ I get an error that my browser can’t connect.

In that tutorial, local host (127.0.0.1) is for folks who have the Sandbox set up on a local VM (VMWare, VirtualBox, etc). It specifically says that "In case of Azure, your host can be found under Public IP Address on the dashboard." Further down in the document it says to use 'ssh <username>@<host> -p 22' to ssh into the Sandbox on Azure. Another document says to set up port-forwarding and log in as 'azure' but it doesn't tell you want azure's default password is so that doesn't 100% work: https://hortonworks.com/hadoop-tutorial/deploying-hortonworks-sandbox-on-microsoft-azure/

Mushtaq Rizvi - This isn't working for me, for HDP 2.5 Sandbox on Azure. See my other post 'Cannot log into Ambari Dashboard for HDP2.5 Azure Sandbox'. Any debugging tips? I tried 'ssh -p2222 root@xx.xx.xx.xx' (where IP is that of my VM). Timed out. Tried 'ssh -p2222 root@127.0.0.1'. Connection refused

Unfortunately, all of the below variants time-out (where xx.xxx.xx.xxxx is my VM's static IP address). Should I not be using that IP address? FYI I posted a question on that Azure article I referenced above. ssh root@xx.xxx.xx.xxx -p 2222 ssh root@xx.xxx.xx.xxx -p 2122 ssh hdfs@xx.xxx.xx.xxx -p 2222 ssh ambari@xx.xxx.xx.xxx -p 2222

yvora - There are no ambari logs at all in /var/log in my HDP2.5 VM; however they do exist in my HDP2.4 VM! Trying to understand the 2 other questions you shared with me. The first seems to suggest I need to run 'ambari-agent-password-reset' as user hdfs, not root? Not clear on that. I've long since changed my root password, if that's all that's about? The other one sounds promising but I'm having trouble understanding it. The Azure VM has a Docker container inside it? Wow! I thought they were competing technologies but I just found this announcement: https://azure.microsoft.com/en-us/blog/running-docker-container-on-azure-batch ! So if I'm understanding correctly, I ssh in on port 2222 to log into the Docker container with the VM? Just tried that though and it didn't work (timed out). Same with 2122 (also mentioned in that post).

Thanks yvora ... but I'm wondering ... if the server and agent are running then howcome the 'ambari-agent-password-reset' can't be found?

Created a new HDP2.5 Sandbox on Azure today. I can log into Ambari Dashboard for my old HDP2.4 Sandox using http://host:8080 or http://host:8888 but not with my new HDP2.5 one. It just times out. I tried ssh'g into my Sandbox to check if Ambari was running and/or start it manually but no luck. Any advice anyone?
