Based on the operating system you use, navigate to the repo file for your system and save it in the/etc/yum.repos.d/directory.   For Red Hat/CentOS/Oracle 5 (add the below lines in /etc/yum.repos.d/cloudera-cdh5)   [cloudera-cdh5] # Packages for Cloudera's Distribution for Hadoop, Version 5, on RedHat or CentOS 5 x86_64 name=Cloudera's Distribution for Hadoop, Version 5 baseurl=http://archive.cloudera.com/cdh5/redhat/5/x86_64/cdh/5/ gpgkey = http://archive.cloudera.com/cdh5/redhat/5/x86_64/cdh/RPM-GPG-KEY-cloudera gpgcheck = 1 For Red Hat/CentOS/Oracle 6 (64-bit)   [cloudera-cdh5] # Packages for Cloudera's Distribution for Hadoop, Version 5, on RedHat or CentOS 6 x86_64 name=Cloudera's Distribution for Hadoop, Version 5 baseurl=http://archive.cloudera.com/cdh5/redhat/6/x86_64/cdh/5/ gpgkey = http://archive.cloudera.com/cdh5/redhat/6/x86_64/cdh/RPM-GPG-KEY-cloudera gpgcheck = 1   After doing this, you can now see the packages listed in yum list cloudera*   Hope this helps.   ...
