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.

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.
