Ambari HDF 3.2.0 failing during deployment of services


I am installing Ambari with HDF 3.2.0 and there is error on deployment of selected services as below: the error is

" Cannot find a valid baseurl for repo: HDF-3.2-repo-1" and during this error it creates a file /etc/yum.repo.d/ambari-hdf-1.repo which is having no entries as below:

[root@ufm yum.repos.d]# cat ambari-hdf-1.repo


name=HDF-3.2-repo-1 baseurl= path=/

enabled=1 gpgcheck=0


name=HDP-UTILS- baseurl=




[root@ufm yum.repos.d]#


Deployment error is below. Can any body guide where is the mistake.

RuntimeError: Failed to execute command '/usr/bin/yum -y install hdf-select', exited with code '1', message: '
 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>


            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

            yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true
Cannot find a valid baseurl for repo: HDF-3.2-repo-1

We see the yum related error:

Cannot find a valid baseurl for repo: HDF-3.2-repo-1


So please check your Yum repository if it has a valid Base URL?

# grep 'baseurl'  /etc/yum.repos.d/*


Check for the HDP repo links in the above output if it is correct?

As in your shared output we see that the "baseurl=" is set to Empty hence you will need to check the Ambari UI to verify if the base repo URL is setup correctly there?

Ambari UI --> Admin --> Stack And Versions -->  Version -->  Manage Versions    

Verify if the URLs are setup correctly there? for your selected OS.
