raise RuntimeError(message)
RuntimeError: Failed to execute command '/usr/bin/yum -y install hdp-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. Disable the repository, 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
4. 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=.skip_if_unavailable=true
Cannot find a valid baseurl for repo: HDP-3.1-repo-4
1、登录数据库修改表
sudo mysql -u root -p
use ambari;
update repo_definition set base_url="http://x.x.x.x/hdp/centos7/3.1.0.0-78/" where repo_name="HDP";
update repo_definition set base_url="http://x.x.x.x/hdp-utils/centos7/1.1.0.22/" where repo_name="HDP-UTILS";
update repo_definition set base_url="http://x.x.x.x/hdp-gpl/centos7/3.1.0.0-78/" where repo_name= "HDP-GPL";
2、删除生成的空的repo文件，并且刷新源
yum clean all && yum makecache
3、然后重启服务，不需要重新注册，页面会自动跳转到step9.
有些情况HDP-GPL为官网地址，还需要再此更新为实际地址，再此重启ambari-server。
