I am relatively new to Hadoop and have been trying to set up a development environment for a project I am involved with (CentOS 6.5 is the OS). I originally set up the environment using Ambari 1.7 and installing the Hortonworks Data Platform version HDP-2.2.0.0-2041.
Now, I am trying to upgrade to Ambari 2.0.1 and HDP-2.2.6.0.
Ambari upgraded with no problems at all. I also was able to register the new version of HDP through the Ambari Manage Version page. That all went fine.
The problem is when I try to finish the upgrade. The instructions say to go from the Admin menu to "Stack and Versions" then the "Versions" tab. There, I am supposed to see my registered versions and a link to complete the upgrade. However, all I get is a blank page.
FYI, I tried multiple browsers to rule out a browser issue. I tried Firefox and Opera. (I've heard that Chrome is no longer supported for CentOS so didn't try that).
Anyone know why this page would just be blank and/or how I can fix it?
Thanks! Tom
BTW, I tried to post images, but I don't have enough reputation points so I can't. You'll have to take my word for it that Manage Versions is showing the correct versions but the Versions tab under Stack and Versions is completely blank.
Have you clicked on button on the picture? Ambari redirects me to Versions page automatically, when I am doing that:
