Re: Unable to Access the cloudera's WEB UI from browser

Hello,

I have figured out the solution for the above stated problem.

I have added a new firewall rule to accept all the incoming connections to the tcp port 7180, and the procedure to change it in the google cloud can be found in the link below:
