How to solve problem with yum when installing new cluster hdf?

I am installing in Centos 7, Ambari 2.7 and HDF 3.2.

All compatible according to the support matrix.

But I get the following error and I don't know how to fix it, someone can help me a little please.

 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

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

As we see a message for yum installation failure which indicates that there is some issue related to yum repos.
May be some of the "/etc/yum.repos.d/*.repo" file is not correct.

Can you please try running the following command manually on the failing host to see if you are able to install this package on your own?

# yum -y install unzip


If it fails then please try to clean the yum DB and then check if you are able to install packages manually ont hat host?

# yum clean all
# yum -y install unzip


If it still fails then please get the "/etc/yum.repos.d/*.repo" from any working node of your cluster (same OS) and then put it on the problematic host then try again.

.

Hello.

I tried installing unzip and it gives me the same error:

yum install unzip

Also perform the clean, try to reinstall it and same error.

I've checked the yum.repos.d folder on all hosts and the only difference is that the host that has the error has one more repository than the rest of the hosts.

ambari-hdf-1.repo
name=HDF-3.2-repo-1
baseurl=
path=/
enabled=1
gpgcheck=0
[HDP-UTILS-1.1.0.22-repo-1]
name=HDP-UTILS-1.1.0.22-repo-1

Hi @Lanic

It looks like you have some repository that's causing the issue.

Can you trying doing a

yum repolist

and see if there exists any repo that is not actually added by you and delete those repo entries by backing up and moving those entries to tmp folder

mv /etc/yum.repos.d/myREpo.repo /tmp/

then execute the yum repolist command again.

Also, try to run: 'yum clean all' then 'yum update' and see if any of these helps

Hi Akhil, i do before yum repolist and this was the result:

status
HDF-3.2-repo-1                                HDF-3.2-repo-1                                                      0

This two repositories:

HDF-3.2-repo-1  

HDP-UTILS-1.1.0.22-repo-1

Dont was added by me, i think that was installed by the mpack.

Are you sure it's a good idea to remove them?

Test also the yum clean and the update before and the result was the same.
