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. stderr: /var/lib/ambari-agent/data/errors-8.txt Traceback (most recent call last): File "/var/lib/ambari-agent/cache/stack-hooks/before-INSTALL/scripts/hook.py", line 37, in <module> BeforeInstallHook().execute() File "/usr/lib/ambari-agent/lib/resource_management/libraries/script/script.py", line 353, in execute method(env) File "/var/lib/ambari-agent/cache/stack-hooks/before-INSTALL/scripts/hook.py", line 34, in hook install_packages() File "/var/lib/ambari-agent/cache/stack-hooks/before-INSTALL/scripts/shared_initialization.py", line 37, in install_packages retry_count=params.agent_stack_retry_count) File "/usr/lib/ambari-agent/lib/resource_management/core/base.py", line 125, in __new__ cls(names_list.pop(0), env, provider, **kwargs) File "/usr/lib/ambari-agent/lib/resource_management/core/base.py", line 166, in __init__ self.env.run() File "/usr/lib/ambari-agent/lib/resource_management/core/environment.py", line 160, in run self.run_action(resource, action) File "/usr/lib/ambari-agent/lib/resource_management/core/environment.py", line 124, in run_action provider_action() File "/usr/lib/ambari-agent/lib/resource_management/core/providers/packaging.py", line 30, in action_install self._pkg_manager.install_package(package_name, self.__create_context()) File "/usr/lib/ambari-agent/lib/ambari_commons/repo_manager/yum_manager.py", line 219, in install_package shell.repository_manager_executor(cmd, self.properties, context) File "/usr/lib/ambari-agent/lib/ambari_commons/shell.py", line 749, in repository_manager_executor raise RuntimeError(message) RuntimeError: Failed to execute command '/usr/bin/yum -y install unzip', 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. 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: HDF-3.2-repo-1 ' stdout: /var/lib/ambari-agent/data/output-8.txt 2018-09-17 13:51:15,473 - Stack Feature Version Info: Cluster Stack=3.2, Command Stack=None, Command Version=None -> 3.2 2018-09-17 13:51:15,476 - Group['hadoop'] {} 2018-09-17 13:51:15,477 - Adding group Group['hadoop'] 2018-09-17 13:51:15,783 - User['zookeeper'] {'gid': 'hadoop', 'fetch_nonlocal_groups': True, 'groups': ['hadoop'], 'uid': None} 2018-09-17 13:51:15,784 - Adding user User['zookeeper'] 2018-09-17 13:51:17,287 - User['ams'] {'gid': 'hadoop', 'fetch_nonlocal_groups': True, 'groups': ['hadoop'], 'uid': None} 2018-09-17 13:51:17,288 - Adding user User['ams'] 2018-09-17 13:51:18,016 - User['ambari-qa'] {'gid': 'hadoop', 'fetch_nonlocal_groups': True, 'groups': ['hadoop'], 'uid': None} 2018-09-17 13:51:18,016 - Adding user User['ambari-qa'] 2018-09-17 13:51:18,866 - File['/var/lib/ambari-agent/tmp/changeUid.sh'] {'content': StaticFile('changeToSecureUid.sh'), 'mode': 0555} 2018-09-17 13:51:18,871 - Writing File['/var/lib/ambari-agent/tmp/changeUid.sh'] because it doesn't exist 2018-09-17 13:51:18,871 - Changing permission for /var/lib/ambari-agent/tmp/changeUid.sh from 644 to 555 2018-09-17 13:51:18,871 - Execute['/var/lib/ambari-agent/tmp/changeUid.sh ambari-qa /tmp/hadoop-ambari-qa,/tmp/hsperfdata_ambari-qa,/home/ambari-qa,/tmp/ambari-qa,/tmp/sqoop-ambari-qa 0'] {'not_if': '(test $(id -u ambari-qa) -gt 1000) || (false)'} 2018-09-17 13:51:18,874 - Skipping Execute['/var/lib/ambari-agent/tmp/changeUid.sh ambari-qa /tmp/hadoop-ambari-qa,/tmp/hsperfdata_ambari-qa,/home/ambari-qa,/tmp/ambari-qa,/tmp/sqoop-ambari-qa 0'] due to not_if 2018-09-17 13:51:18,884 - Repository['HDF-3.2-repo-1'] {'append_to_file': False, 'base_url': '', 'action': ['create'], 'components': [u'HDF', 'main'], 'repo_template': '[{{repo_id}}]\nname={{repo_id}}\n{% if mirror_list %}mirrorlist={{mirror_list}}{% else %}baseurl={{base_url}}{% endif %}\n\npath=/\nenabled=1\ngpgcheck=0', 'repo_file_name': 'ambari-hdf-1', 'mirror_list': None} 2018-09-17 13:51:18,896 - File['/etc/yum.repos.d/ambari-hdf-1.repo'] {'content': InlineTemplate(...)} 2018-09-17 13:51:18,896 - Writing File['/etc/yum.repos.d/ambari-hdf-1.repo'] because it doesn't exist 2018-09-17 13:51:18,896 - Repository['HDP-UTILS-1.1.0.22-repo-1'] {'append_to_file': True, 'base_url': '', 'action': ['create'], 'components': [u'HDP-UTILS', 'main'], 'repo_template': '[{{repo_id}}]\nname={{repo_id}}\n{% if mirror_list %}mirrorlist={{mirror_list}}{% else %}baseurl={{base_url}}{% endif %}\n\npath=/\nenabled=1\ngpgcheck=0', 'repo_file_name': 'ambari-hdf-1', 'mirror_list': None} 2018-09-17 13:51:18,898 - File['/etc/yum.repos.d/ambari-hdf-1.repo'] {'content': '[HDF-3.2-repo-1]\nname=HDF-3.2-repo-1\nbaseurl=\n\npath=/\nenabled=1\ngpgcheck=0\n[HDP-UTILS-1.1.0.22-repo-1]\nname=HDP-UTILS-1.1.0.22-repo-1\nbaseurl=\n\npath=/\nenabled=1\ngpgcheck=0'} 2018-09-17 13:51:18,898 - Writing File['/etc/yum.repos.d/ambari-hdf-1.repo'] because contents don't match 2018-09-17 13:51:18,899 - Package['unzip'] {'retry_on_repo_unavailability': False, 'retry_count': 5} 2018-09-17 13:51:18,946 - Installing package unzip ('/usr/bin/yum -y install unzip') 2018-09-17 13:51:19,087 - Skipping stack-select on AMBARI_METRICS because it does not exist in the stack-select package structure.
