22. 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 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
  3. Synchronize Database

    cd /usr/lib/hue
    source ./build/env/bin/activate
    hue syncdb
  4. Start Hue. As a root user, run the following command on the Hue Server:

    /etc/init.d/hue start
