I'm currently working on CDH5.13 (Cloudera Distribution Hadoop), and i have a couple of questions:   1- I want to get the latest version of CDH(6.3.3). When i try to download it, i have this message (Your MyCloudera account is not currently connected with a CDH subscription which is required for CDH 6.3.3 and later.). Where do I go to get a subscription? And what is the cost of the subscription?    2- I tried to download older versions of CDH, but it says ( As of February 1, 2021, all downloads of CDH and Cloudera Manager require a username and password and use a modified URL. You must use the modified URL, including the username and password when downloading the repository contents described below.). I'm assuming i have to get a license to have this username and password. Where should I go to buy this?   3- I also tried to download Hortonworks Data Platform, but i have this message (You must be a HDP customer to access these downloads. If you believe you should have access to these then please reach out to support or your customer service representative.). How to become an HDP customer? And what is the cost?   4- I managed to donwload Hortonworks Data Platform Sandbox, so i'm assuming it's free, but i must become a HDP customer to download Hortonworks Data Platform. So what's the difference between these two?   Sorry for the long message and thank you in advance for your answers. ... View more

Im trying to install the trial version of CDP Data Center on my linux (ubuntu 18.04) virtual machine.
