Description

Ambari has removed its native support of distributing and installing LZO when the LZO codecs are enabled in core-site. For existing clusters where LZO is enabled, this means that performing an upgrade will now require manual user intervention to get the LZO packages installed.

A pre-upgrade check should be created which checks to see if LZO is enabled in the cluster and then produces a WARNING to the user letting them know that before upgrading, they'd need to distribute the appropriate LZO packages.
