Ensure that you complete the following instructions before upgrading Ambari server:
Ensure that all the services are started (indicated by green color on the dashboard) before you upgrade Ambari.
Ensure that you start all those services that are currently stopped.
Do not upgrade if all the services are not started. This issue is expected to be fixed in the next release version of Ambari.
Stop the Ambari Server and all Ambari Agents. From the Ambari Server host:
ambari-server stop
From each Ambari Agent host:
ambari-agent stop
If the
conf.save
directory exists on the Ambari server and agents, move this directory (for both Ambari server and agents) to a back up location:mv /etc/ambari-server/conf.save/ /etc/ambari-server/conf.save.bak
mv /etc/ambari-agent/conf.save/ /etc/ambari-agent/conf.save.bak
