Below are the sequence of steps:

  1. stop all the services in cluster and stop clouderamanager and agent packages.

  2. Take the cm datbase backup for safer side.

  3. Update JDK if required. I have installed JDK1.8.

  4. Update the repo file with the latest version as below .

    cloudera-cdh5]

    Packages for Cloudera's Distribution for Hadoop, Version 5, on RedHat or CentOS 7 x86_64

    gpgcheck = 1

  5. Do all the sanity checks before upgrade like selinux, firewall settings.
