Hi @Avraha Zilberman, what machine did you choose for Sandbox offering on Azure A4? Also, I would like to suggest if you can edit your previous posting of the error and just have a small snippet of the error stack and put the full log in a file. It will prevent having to scroll down to get to the next post.

@Avraha Zilberman you need to make sure your endpoints are open for hbase and all other products. Please look at our documentation for port information. The doc is for Windows but should be applicable for ports on Linux as well. Is your firewall up?
