Today we will see how we can resolve the error “sandbox.hortonworks.com’s server DNS address could not be found” while loading Oozie Web UI. I got this wired error after reinstalling the HDP sandbox on Windows 10.
This error is happening because we haven’t updated the hosts file in Windows 10 platform. You can find the hosts file under the below listed directory.
Copy the host file to desktop and then edit it, add the following line at the end of hosts file.
Now copy back the hosts file to C:\Windows\System32\drivers\etc, You may need the admin rights if you are not a power user.
Now you will be able to access Oozie UI with the below link.
