Upgrading CDH in a Cloudera Manager Deployment

  Important:

Cloudera Manager version 3.x and CDH3 have reached End of Maintenance (EOM) as of June 20, 2013. Cloudera will not support or provide patches for any of the Cloudera Manager version 3.x and CDH3 releases. Even though Cloudera Manager 4.x will continue to support CDH3, it is strongly recommended that you upgrade to CDH4. See Upgrading existing installations of CDH3 to CDH4 for more details.
