What is the industry standards or process to install patches for bug/fixes on Cloudera CDH cluster?
Does anyone have any document or reference for overall process/life cycle?
Patches/fixes are applied to a CDH cluster by the way of "parcels". Cloudera regularly releases new parcels that include improvements and fixes to all the CDH components. The process to upgrade to a new parcels is described here: https://www.cloudera.com/documentation/enterprise/upgrade/topics/ug_overview.html
Thanks. The article says about upgrading and updating CDH for major/minor releases. What I am looking for a specific patch/fix for any issue that is encountered in your cluster for which either support is need from Cloudera or we have a patch available at JIRA/GIT repository. Any further information on the roles and responsibility as an Hadoop administrator for applying such patches either from CLI (using "patch" commands, GIT repo sync etc.)?
