BUG-19511: Error message during Hue start after upgrading Hue

Problem: After upgrading Hue from Hue 2.3.0 to Hue 2.3.2 and restarting the service, Hue displays

Failed to register some apps: Details in /var/log/hue/hue_re_register.log

The message is benign, and can be ignored.

chown -R hue:hue /usr/lib/hue

BUG-19502: Hue does not ship hive.aux.jars.path

Problem: Hue does not ship hive.aux.jars.path. This can cause problems with hbasestorage tables.

Workaround: To place the HBase jars on the Hue server host, enter:

ln -s /usr/lib/hbase/lib*.jar /usr/lib/hive/lib/
ln -s /etc/hbase/conf/*.xml /etc/hive/conf/
