Getting oracle-j2sdk1.7 installation failed while installing CDH5

[#1]

Hello All , 

I get this error 
oracle-j2sdk1.7 installation failed. See /var/log/cloudera-manager-installer/2.install-oracle-j2sdk1.7.log for details. Click OK to revert this installation.
When i try to install CDH5 .I checked the log file it was mentioned as 
Loaded plugins: fastestmirror, refresh-packagekit, security Loading mirror speeds from cached hostfile Error: Cannot find a valid baseurl for repo: base Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os error was 14: PYCURL ERROR 7 - "Failed to connect to 2a02:2498:1:3d:5054:ff:fed3:e91a: Network is unreachable"

OS : Centos 6.4 

Please provide me a solution to intall the same

Sounds like a problem with the mirror with the centos mirror. Are you able
to reach the URL directly from the machine (say via ping/wget/etc.)? If so,
try again perhaps?

Yes I tried to access the link http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os in firefox browser . It worked . But yet i get this error

The error is from yum, so I suggest looking for answers there.  A web search turned up various hits for yum and IPv6.  This one seemed to have the most suggestions:

This backs up the suggestion that it may be a problem with the firewall:

Once the yum/network issue is resolved, the installation should proceed.

Maybe shut off iptables ( service iptables stop ) and then run the install.  If the network/yum can't get ironed out, then you may need to use Path B or C install rather than the "bin" install.

See http://www.cloudera.com/content/cloudera-content/cloudera-docs/CM5/latest/Cloudera-Manager-Installat...

Hello All ,
Thanks for your response .
I got it solved . My ultimate end was to start the cloudera manager . It worked .
I just disabled the iptables by
[root@INCHCMPCCHE01 cloudera-scm-server]# /etc/init.d/iptables save
iptables: Saving firewall rules to /etc/sysconfig/iptables:[ OK ]
[root@INCHCMPCCHE01 cloudera-scm-server]# /etc/init.d/iptables stop
iptables: Flushing firewall rules: [ OK ]
iptables: Setting chains to policy ACCEPT: nat mangle filte[ OK ]
iptables: Unloading modules: [ OK ]

Thank you 🙂

Hi ,

got same error while try to add hosts through cloudera manager.

Error: Cannot find a valid baseurl for repo: base
Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os&infra=stock error was
14: PYCURL ERROR 7 - "Failed to connect to 2a02:2498:1:3d:5054:ff:fed3:e91a: Network is unreachable"

-In host machine

* CentOS 6.6 (Final)

* firewall turn off

* yum update working fine

Here we are using proxy ...  proxy settings configured with /etc/yum.conf
