> +Question:+
> Error on starting the application Puppet in the Generic enablers Cosmos
> +Description:+
> Good afternoon, 
> I have installed the Generic enablers Cosmos, following the manual BigData Analysis - Installation and Administration Guide. When I have come to 'Step 7: applying Puppet' and executed the commands, in the file puppet.err has appeared the following errors:
> Error: Could not prefetch yumrepo provider ' inifilé: Section 'openvz-utils' is already defined, cannot re-defines in/etc/yum.repos.d/openvz.repo
> Description: There is a conflict with the titles (indicated in bold type) of the file /etc/yum.repos.d/cosmos-openvz.repo and /etc/yum.repos.d/openvz.repo .
> cat /etc/yum.repos.d/cosmos-openvz.repo
>   [openvz-utils]
>   ...
>   
>   [openvz-kernel-rhel6]
>   ... 
> cat /etc/yum.repos.d/openvz.repo
>   [openvz-utils]
>   ...
>   
>   [openvz-kernel-rhel6]
>   ...  
>   
>   [openvz-kernel-rhel6-testing]
>   ...
> Solution: I have realized a change in the titles of the file /etc/yum.repos.d/openvz.repo, example: [openvz-utils_1]
> Error: Could not prefetch database_grant provider 'mysql': Execution of '/usr/bin/mysql mysql -Be describe user' returned 1: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
> Description: in the folder /var/lib/mysql/ was not found the file mysql.sock.
> Solution: I have installed mysql-server.x86_64:
>   yum install mysql-server.x86_64
> At the end of the installations, I restarted the service: 
>   /etc/init.d/mysqld stop
>   /etc/init.d/mysqld start
> Error: Could not update: Execution of '/usr/bin/yum -d 0 -e 0 -y list vzstats' returned 1: Error: Cannot retrieve repository metadata (repomd.xml) for repository: ambari. Please verify its path and try again
> Description: This error appears in the machine of the Master node, this one is provoked by the configuration of the file [COSMOS_TMP_PATH]/puppet/modules/cosmos/manifests/hieradata/my_environment/common.yaml, indicated in 'Step 6: Puppet configuration'. Concretely, the URL that use the IP: 130.206.81.65 
> Solution: in the file [COSMOS_TMP_PATH]/puppet/modules/cosmos/manifests/hieradata /my_environment/common.yaml to change the line:
>   ambari::params::repo_url: 'http:// 130.206.81.65/cosmos/ambari/'  
> (without blank space)
> for
>   ambari::params::repo_url: 'http:// public-repo-1.hortonworks.com/ambari/centos6/1.x/GA'  
> (without blank space)
> Error: Could not update: Execution of '/usr/bin/yum -d 0 -e 0 -y list vzstats' returned 1: Error: Cannot retrieve repository metadata (repomd.xml) for repository: cosmos-libvirt. Please verify its path and try again
> Description: it is the same problem as the previous error. The difficulty in this one is that I cannot modify the file [COSMOS_TMP_PATH]/puppet/modules/cosmos/manifests/hieradata /my_environment/common.yaml in the line: 
>   cosmos::params::cosmos_repo_deps_url: 'http:// 130.206.81.65/cosmos/rpms/cosmos-deps'  
> (without blank space)
> Because it is line is used in several files:
> cat /etc/yum.repos.d/cosmos-libvirt.repo
>   [cosmos-libvirt]
>   name=Cosmos LibVirt with OpenVZ - v1.0.5 - NO PolKIT
>   baseurl=http:// 130.206.81.65/cosmos/rpms/cosmos-deps//libvirt
>   gpgcheck=0
>   priority=10
>   enabled=1  
> cat /etc/yum.repos.d/cosmos-openvz.repo
>   [openvz-utils]
>   name=OpenVZ utilities
>   baseurl=http:// 130.206.81.65/cosmos/rpms/cosmos-deps//OpenVZ/openvz-utils
>   enabled=1
>   gpgcheck=0
>   priority=1  
>   
>   [openvz-kernel-rhel6]
>   name=OpenVZ RHEL6-based kernel
>   baseurl=http:// 130.206.81.65/cosmos/rpms/cosmos-deps//OpenVZ/openvz-kernel- > rhel6
>   enabled=1
>   gpgcheck=0
>   priority=1  
> It does not also allow to modify the file previous, in the moment to execute the command (indicated in 'Step 7: applying Puppet'):
>   puppet apply --debug --verbose \
>    --modulepath [COSMOS_TMP_PATH]/puppet/modules/:[COSMOS_TMP_PATH]/puppet/modules_third_party/ \
>    --environment my_environment --hiera_config [COSMOS_TMP_PATH]/puppet/modules/cosmos/manifests/hiera.yaml \
>    --manifestdir [COSMOS_TMP_PATH]/puppet/modules/cosmos/manifests/ [COSMOS_TMP_PATH]/puppet/modules/cosmos/manifests/site.pp \
>    > puppet.out 2> puppet.err  
> It will erase the modified.
> Solution: https://github.com/telefonicaid/fiware-cosmos-platform/issues/4
> I need help with the error:
> Error: /Stage[main]/Ambari::Server::Config/Augeas[ambari-config-repoinfo]: Could not evaluate: Saving failed, see debug
> Might they to throw me a hand with these last error? 
> Thank you in advance.
> PD: Forgive for if it is written badly
