RuntimeError: Failed to execute command '/usr/bin/yum -y install hdp-select', exited with code '1', message: 'Repository InstallMedia is listed more than once in the configuration

 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

此時想必你已經到了安裝步驟9了，

而且你觸發了hdp離線安裝才會觸發的BUG，

 

了解下出了什么問題：

簡單說就是ambari前端代碼在檢測到無法連接到互聯網時，會自動創建ambari-hdp-1.repo文件，但創建的文件中的鏈接是從數據庫讀取的，數據庫里沒有配置相關的下載鏈接，

https://community.cloudera.com/t5/Support-Questions/HDP-3-0-with-local-repository-failing-to-deploy/td-p/240954

https://community.cloudera.com/t5/Community-Articles/ambari-2-7-3-Ambari-writes-Empty-baseurl-values-written-to/ta-p/249314

 

可以看到ambari-hdp-1.repo文件內容：

[HDP-3.1-repo-1]
name=HDP-3.1-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
baseurl=


path=/
enabled=1
gpgcheck=0

 

嘗試檢測：

Could you please check the repos are correct in host where the installation is failing

# grep 'baseurl' /etc/yum.repos.d/* | grep -i HDP
Try cleaning the yum cache by running the command.

# yum clean all
Please check if in case of any multiple "ambari-hdp-<repoid>.repo" files present inside the "/etc/yum.repos.d/" . If so, then move the unwanted files from there to back up folder.

Please try the below commands from the host where it is failing to install "hdp-select" package

# yum install hdp-select -y

 

嘗試解決：

下面的方法先說的是如果你安裝完成或者還沒開始安裝的情況下的處理辦法，

安裝到步驟9的你，需要的辦法再繼續向后看，千萬別直接reset了，

Root cause : https://issues.apache.org/jira/browse/AMBARI-25069

Workaround :

This is a Javascript bug in ambari that happens when using local repository and there is no internet access to cluster

to workaround this

Steps

1) go to /usr/lib/ambari-server/web/javascipts

cd /usr/lib/ambari-server/web/javascripts
2) take backup of app.js

 cp app.js app.js_backup
3) edit the app.js

find out the line(39892) : onNetworkIssuesExist: function () {

Change the line from :

  /**
   * Use Local Repo if some network issues exist
   */
  onNetworkIssuesExist: function () {
    if (this.get('networkIssuesExist')) {
      this.get('content.stacks').forEach(function (stack) {
          stack.setProperties({
            usePublicRepo: false,
            useLocalRepo: true
          });
          stack.cleanReposBaseUrls();
      });
    }
  }.observes('networkIssuesExist'),
to

  /**
   * Use Local Repo if some network issues exist
   */
  onNetworkIssuesExist: function () {
    if (this.get('networkIssuesExist')) {
      this.get('content.stacks').forEach(function (stack) {
        if(stack.get('useLocalRepo') != true){
          stack.setProperties({
            usePublicRepo: false,
            useLocalRepo: true
          });
          stack.cleanReposBaseUrls();
        } 
      });
    }
  }.observes('networkIssuesExist'),
as per : https://github.com/apache/ambari/pull/2743/files

如果你還沒安裝，或者已經安裝完了，

Later as you have already deployed the cluster we need to reset the cluster (Caution : this will erase all the configs you have created previously in Step6 and also the Hosts and services you have selected need to select again )

Command :

ambari-server reset
And hard reload the page and start the create cluster wizard again.

如果你已經安裝到了步驟9，

Incase you have already at Step 9 and cannot proceed with ambari-server reset (as it invovles lots of Configs being added again , the below steps are for you )

Preqrequesties : The cluster now is in Deployment step(step 9 ) and you have only retry button to press

steps

1) Stop ambari-server

2) login to Database

3) use the below command to list out all the contents in repo_definition table :

 select * from repo_definition; 
4) you can see the base_url will be empty for the all the Rows in the table

5) Correct the base_url for every rows and update it using the command :

update repo_definition set base_url='<YOUR BASE URL>' where id=<THE CORESPONDING ID>;
for ex :

update repo_definition set base_url='http://asnaik.example.com/localrepo/HDP-3.1' where id=9;
6) after correcting all the base_url columns in repo_definition table and also delete the empty repos created by ambari from location /etc/yum.repos.d

7) start ambari, Login to UI and press retry button, The Installation will work as smooth as it can be.

Hope this helps.

 

親測方法可以解決，也不要怕修改ambari的代碼，
