Hi, After success installation of Metron mpack, i Am unable to see Metron services in ambari. And i am getting below error while installing Repo. [root@devupgnew1 ~]# yum install createrepo ( at Ambari host) http://public-repo-1.hortonworks.com/HDP-UTILS-1.1.0.22/repos/centos7/repodata/repomd.xml: [Errno 14] curl#6 - "Could not resolve host: public-repo-1.hortonworks.com; Unknown error" Trying other mirror. One of the configured repositories failed (HDP-UTILS-1.1.0.22-repo-101), 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=HDP-UTILS-1.1.0.22-repo-101 ... 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 HDP-UTILS-1.1.0.22-repo-101 or subscription-manager repos --disable=HDP-UTILS-1.1.0.22-repo-101 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=HDP-UTILS-1.1.0.22-repo-101.skip_if_unavailable=true failure: repodata/repomd.xml from HDP-UTILS-1.1.0.22-repo-101: [Errno 256] No more mirrors to try. http://public-repo-1.hortonworks.com/HDP-UTILS-1.1.0.22/repos/centos7/repodata/repomd.xml: [Errno 14] curl#6 - "Could not resolve host: public-repo-1.hortonworks.com; Unknown error" what is the issue here.
