Pramod - I didn't have your above error message.
Are you able to see the Welcome Home page on firefox after signing in into Hue?

As for the installation I just went to cloudera website the same link the instructor shared with us and just followed the instruction.
First I installed Oracle VM VirtualBox it (GUI-based) then I installed cloudera. At the end of the installtion process you should see VirtualBox with cloudera VM that you can start through the GUI.

I had this issue and had to Enable virtualization which is done in bios settings. If you have a Lenovo hit enter just after restarting and enter bios settings. Combination of keys to reach bios usually shows on the black screen on startup. .

hi Pramod,
You don't have to install cloudera. You need to load the cloudera VM in Virtualbox (download from virtualbox.net).

Thanks

Thank Hafid and Shivjit .

Can you please provide me the link for Oracle VM Virtual box(and also if there are any further links ). Thank you

I was able to install the Cloudera VM in Virtual box. Thanks for all your suggestion.

I also found a youtube link which is more self explained. If anyone are interested, pl take a look.
