Hi @Gaurav Sarin You might have a closed port issue. The Sandbox, by default, comes with only certain ports open. There are some guides on how to add additional ports that you may want to follow to get port 7070 accessible for Kylin. Do follow the tutorials as just opening the port within the outer virtualization software is not enough, they need to be open within the internal Docker layer as well. From the link below, pick your VM software and click Next for the step by step instructions. https://hortonworks.com/tutorial/sandbox-port-forwarding-guide/ ... View more

Hi @Sahil Jindal It seems you have tried to address the most common causes already. This may sound silly, but I've seen it happen three times now.

hi @Sahil Jindal I just tried to download the VirtualBox HDP 2.6 sandbox using Chrome. I filled out the form, and when I submitted it, after about 2-3 seconds, the file download began and my browser prompted me to save the file. If you are able to try from a different machine (are file downloads that large prevented by your IT policies?), that might be a good test. It does appear to be working correctly. ... View more

hi @Vikas Malviya I would recommend you get started by looking the tutorials provided on the Hortonworks website. While they may be designed for the HDP Sandbox, you can likely still follow them on your own cluster. https://hortonworks.com/tutorials/ Good luck on your big data journey! ... View more
