ODP Stack Upgrade
This document provides a complete walkthrough of the process for upgrading your stack using Ambari.
Run Service check for All Services
Perform the sanity test for each service.
Disable the Service Auto Restart
To prevent services from restarting automatically during the upgrade, disable the service auto-restart option in Ambari.
Back Up Databases
Before proceeding with the upgrade, ensure that all backend databases are backed up. Since MySQL is used as the backend database in this case, run the following commands to create the backups:
mkdir /tmp/ODP-server_db_bckp/
cd /tmp/ODP-server_db_bckp/
# for ambari
mysqldump --databases ambari > /tmp/ODP-server_db_bckp/ambari_mysql_bckp.sql
# for hive
mysqldump --databases hive > /tmp/ODP-server_db_bckp/hive_mysql_bckp.sql
# for rangerkms
mysqldump --databases rangerkms > /tmp/ODP-server_db_bckp/rangerkms_mysql_bckp.sql
# for rangerkms
mysqldump --databases ranger > /tmp/ODP-server_db_bckp/ranger_mysql_bckp.sql
# please take backup for all required services
