- Do you mean HDP 3.0 or HDF 3.0 ? (They are different).

- Also please check if the "iptables" is stop.

If you are using HDP:

- Are you able to open http://localhost:4200 ?

- Have you tried reimporting the Sandbox Image?

- Have you checked if your VirtualBox instance has the proper Port Forwarding enabled? https://hortonworks.com/tutorial/sandbox-port-forwarding-guide/section/1/

.

If you are using HDF3.0 then please try:

http://localhost:18888

-When run virtual box i am getting url for browser http://127.0.0.1:8888/

-My installation was fine in HDP 3.0 i was getting invalid setting for VTx and memory that have been solve after enabling VTx in bios and with new memory selection these had been resolved.

-After that when i am trying to connect http://127.0.0.1:8888/ at crome , Mozilla or safari getting the same status that site not found.

Looks like you are setting 4GB ram for your Sandbox instance, However according to the doc you should set it to 8GB to function properly.

Please refer to the following note from the link: https://hortonworks.com/tutorial/sandbox-deployment-and-install-guide/section/1/

Note: Make sure to allocate at least 8 GB (8192 MB) of RAM for the sandbox.

.

Some services might now have started properly. Can you please check the port 8888 is actually opened in the sandbox from the SSH window?

# netstat -tnlpa | grep 8888

.

@ Jay Sen Sharma (Guru)

in my system i have 8gb total ram and when trying to allocate more than 5208 mb it's showing invalid setting and ok button have been disable and can't save forcefully.

invalid setting notification is-

''more than 88% of host computer memory 7.93 gb is assigned to virtual mechine. Not enough memory left for the host operating system. Please select smaller amount.''

In sandbox when try to run command like ipconfig it's showing command not found.

It's refusing when trying to connect ssh.

Is i have to reinstall virtual box again ?? or i can do some more troubleshoot with it. Either it's laptop memory issue.

please suggets..capture2.pngcapture3.pngcapture4.pngcapture5.pngcapture6.png

Please make sure to use the "SSH Port 2222" only when trying to connect to Sandbox. (IN windows while using Putty to do ssh please choose ssh port as 2222), then your commands like "ifconfig" and "netstat" and other commands will start working. Or try using Web Console using "http://localhost:4200" (you can replace the localhost with the sandbox hostname if you have changed it)

In Linux environment you can use the following command to do ssh to Sandbox:

# ssh root@localhost  -p 2222

- Also in your "21401-capture8.png" screenshot it looks like inside the Sandbox SSH session you are trying to do ssh again to port 2222 which is not right.

You need to do SSH on port 2222 from your Windows to Sandbox. (Not inside the Sandbox terminal)

.

- Regarding 4GB (5GB) RAM, i will suggest you to have a system with more RAM so that you can create use HDP sandbox image with 8GB ram, Else some of the in the HDP sandbox might not be working well.

but nothings work so please help me what the way i can connect sand box 2.6 ...

Is that any issue with memory for hdp 2.6 because as i know every where i get that i can work with hdp 2.5 with minimum 8gb ram but not any information of minimum memory for hdp 2.6.

I already paid udemy classes for hadoop learning tutorial and they use hortonworks so i want to go with hortonwork .
