Pre-Upgrade Steps for Hue

Complete the following steps before you upgrade Hue with or without the Installer.

About this task

Procedure

Stop the Hue service:
maprcli node services -name hue -action stop -nodes <ip_address>

Create a Hue database dump as a JSON object:

For MySQL, PostgreSQL, or Oracle

source /opt/mapr/hue/hue-<version>/bin/activate
hue dumpdata > ~/dump-hue-<version>.json
deactivate

For SQLite

cd /opt/mapr/hue/hue-<version>/desktop
sqlite3 desktop.db .dump > ~/dump-hue-<version>-sqlite.bak

Copy the configuration properties from /opt/mapr/hue/hue-<version>/desktop/conf/ to a location outside your installation directory.
After upgrading, you can reapply changes to the updated Hue installation using the backup.
After upgrading on Ubuntu, remove the mapr-hue-base package:
```
apt-get remove mapr-hue-base
```

Preserving Hue Configuration

Starting from EEP-6.0.0, preserving of user configuration logic is built into Hue.

Procedure

For a major version update (for example, Hue-3.2-1803 to Hive-4.2-1808), user configuration from a previous version is only copied to a folder with an old version timestamp (/HUE_HOME/hue-3.12.0.201707281202).
