Chapter 7. Appendix: Upgrading Operating Systems on an Ambari-based Hadoop Installation

Ambari requires specific versions of the files for components that it uses. There are three steps you should take to make sure that these versions continue to be available:

  • Disable automatic OS updates

  • Do not update any HDP components such as MySQL, Ganglia, etc.

  • If you must perform an OS update, do a manual kernel update only.
