However, was not working.

So I now have the following:



However, I am still getting an error when I go to

Can you please assist with this? Thanks a lot.


Re: Unable to initiate Hortonworks Sandbox session



I have just downloaded a Virtual box sandbox image and imported it into the VirtualBox successfully. In my configuration, I  enabled only one network card Bridge Adapter so it picks the IP from my LAN of 192.168.0.x


After uncompressing the Docker image, the initial screen shows it picked my local LAN IP which I used to access the browser CLI as shown below.  Make sure you update your  windows hosts file in C:\Windows\System32\drivers\etc

I completed the below steps changing the initial root password Hadoop and then reset the Ambai user password. Once that is successful is starts the Ambari server

DB configs consistency check: no errors and warnings were found. 


Using the Local IP given to the VirtualBox from my LAN,I could access Ambari with the new password I reset above and restarted all serive though some were running.


Can you confirm you followed those steps and still failed??

Happy hadooping
