I have a problem when I am reviewing the cluster in the CLUSTER INSTALL WIZARD

[#1]

Hi everyone!

I am trying to create a cluster and in the "step 8 : Review" I get the next error when I click on the "Deploy -->" button:

"Upload Version Definition File Error"

"An internal system exception occurred: Base url http://public-repo-1.hortonworks.com/HDP/sles12/2.x/updates/2.5.0.0 is already defined for another repository version. Setting up base urls that contain the same versions of components will cause stack upgrade to fail."

What does it happen? What can I do to solve the problem?

Thank you so much!

Hi All,

I am having this same issue and I have tried some of the recommendations above with negative results. I am trying to stand up an HDP 2.4 cluster on centos7. In my experience, I get passed all of the assigning of roles to my name and datanodes and hit deploy. Everything looks like it's going smoothly and then I get smacked with the "Upload Version Definition File Error". At this point things are stalled. I check to see if my ambari-server is still running and it isn't. I try to restart it and I get a postgres "exit code 3. REASON: Unable to start PostgreSQL server". I've tried to reset the server, dump the database, un/re-install ambari-server, and even select the other than default postgres during the setup with same result. Can anyone help? Thanks.
