21. Configure and Start Hue

For HDP 2.2, use the Hue version shipped with HDP 2.2. If you have a previous version of Hue, use the following steps to upgrade Hue.

  1. Migrate the hue.ini setting from your old hue.ini configuration file to new hue.ini configuration file.

  2. If you are using the embedded SQLite database, remember to restore your database after upgrade.

    To restore the database from a backup, make sure the destination database is empty before copying (if necessary, rename or remove the current destination database), then copy your backup to the destination database.

    For example:

    su $HUE_USER

    cd /var/lib/hue

    mv desktop.db desktop.db.old

    sqlite3 desktop.db < ~/hue_backup/desktop.bak

    exit

  3. Synchronize the database:

    cd /usr/lib/hue

    source ./build/env/bin/activate

    hue syncdb

    deactivate

  4. Start Hue. As a root user, run the following command on the Hue Server:

    /etc/init.d/hue start
