I just downloaded the most recent release of the sandbox and tried to load the built in Zeppelin view. I got an error(see attached picture) that said "Unable to resolve the server's DNS Address" when you hovered over it. The rest of the install went cleanly but I am wondering how to fix this default view. Also how would I raise this as a ticket?screenshot-from-2016-01-17-171207.png
Thanks for the quick answer. Didn't think to check the sandbox's release notes instead of just general HDP release notes.
