    Details

      Description

      when using a local repository, installation fails due to empty baseurls being written to the Ambari repository (even though local repository baseurl values were provided). The installation fails with below error :

      stderr:

       One of the configured repositories failed (Unknown),
       and yum doesn't have enough cached data to continue. At this point the only
       safe thing yum can do is fail. There are a few ways to work "fix" this:
       
           1. Contact the upstream for the repository and get them to fix the problem.
       
          2. Reconfigure the baseurl/etc. for the repository, to point to a working
       
             upstream. This is most often useful if you are using a newer distribution release than is supported by the repository (and the packages for the previous distribution release still work).
       
           3. Run the command with the repository temporarily disabled
       
                  yum --disablerepo=<repoid> ...
       
           4. Disable the repository permanently, so yum won't use it by default. Yum will then just ignore the repository until you permanently enable it again or use --enablerepo for temporary usage:
               yum-config-manager --disable <repoid>
      
              or 
                  subscription-manager repos --disable=<repoid>
      
           5. Configure the failing repository to be skipped, if it is unavailable.
      
              Note that yum will try to contact the repo. when it runs most commands,so will have to try and fail each time (and thus. yum will be be much slower). If it is a very temporary problem though, this is often a nice
      
              compromise:
      
                  yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true
       
      Cannot find a valid baseurl for repo: HDP-3.1-repo-1
      '
      Command aborted. Reason: 'Server considered task failed and automatically aborted it'
       stdout:
      

      We can See that Ambari UI shows the empty baseURL in review step

      It also sends the empty Repo version while deploy stage
