Pre-Upgrade Steps for Livy
About this task
Use these steps:
- Stop the Livy service if it is
installed:
maprcli node services -name livy -action stop -nodes <ip_address>
- If necessary, back up configuration files:If you made configuration changes that you want to carry over to the next version, you need to back up the configuration files. Typically, the following configuration files contain changes:
/opt/mapr/livy/livy-<version>/conf/livy.conf
/opt/mapr/livy/livy-<version>/conf/livy-env.sh
To back up configuration files, copy the files to a location outside the installation directory. After upgrading, you can reapply changes to the updated Livy installation using the backup.
NOTE
- Starting from EEP-6.0, for Livy upgrades, from Livy 0.3 and above, user configuration files are saved during upgrade.
- For Livy upgrades from
mapr-hue-livy 3.12
, user configuration files are NOT saved during the upgrade. - For manual Livy upgrades from
mapr-hue-livy 3.12
on Ubuntu, you need to remove the oldmapr-hue livy
package manually.
