I am installing CDH 5.1.0 Hadoop in my RHEL 6.1 cluster using Cloudera Manager. I don't have direct Internet connectivity but I do have a proxy server with port 80 which allows me to connect Internet. I checked the connectivity configuring proxy IP and Port in wget command and it is working.
I downloaded cloudera-manager-installer.bin and when i proceed with installation it tries connecting Internet for downloading Java and other intallables, but fails connecting to internet.
Where should I configure this proxy IP so that my cloudera manager takes this proxy and gets connected to Internet.
We typically tell customers to avoid installations using path A and use path B especially if you expect this POC or test environment to later move into production. As a best practice it is generally better to operate Cloudera Manager on it's own system using an external database structure such as postgresql or mysql. If you would like to continue with path A please see the information in the article below which outlines what must be changed in order to use a proxy with this install path. As you can see in the help documentation, you will need to configure yum so that it can use a proxy.
You also have the option of creating your own mirror or Local repository.
