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.

此时想必你已经到了安装步骤9了，
而且你触发了hdp离线安装才会触发的BUG，
了解下出了什么问题：
简单说就是ambari前端代码在检测到无法连接到互联网时，会自动创建ambari-hdp-1.repo文件，但创建的文件中的链接是从数据库读取的，数据库里没有配置相关的下载链接，
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文件内容：
[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
尝试检测：
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
尝试解决：
下面的方法先说的是如果你安装完成或者还没开始安装的情况下的处理办法，
安装到步骤9的你，需要的办法再继续向后看，千万别直接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
如果你还没安装，或者已经安装完了，
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. 如果你已经安装到了步骤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.
亲测方法可以解决，也不要怕修改ambari的代码，
诸业皆是自作自受，休咎祸福，尽从心生。
