Configure Kerberos as described in Setting Up Security for Manual Installs.

Create a principal for the Hue Server.

addprinc -randkey hue/$FQDN@EXAMPLE.COM

where $FQDN is the hostname of the Hue Server and EXAMPLE.COM is the Hadoop realm.

Generate a keytab for the Hue principal.

xst -k hue.service.keytab hue/$FQDN@EXAMPLE.COM

Place the keytab file on the Hue Server. Set the permissions and ownership of the keytab file.

/etc/security/keytabs/hue.service.keytab 
chown hue:hadoop /etc/security/keytabs/hue.service.keytab 
chmod 600 /etc/security/keytabs/hue.service.keytab 

Confirm the keytab is accessible by testing kinit.

su - hue kinit -k -t /etc/security/keytabs/hue.service.keytab hue/$FQDN@EXAMPLE.COM

Add the following to the [kerberos] section in the /etc/hue/conf/hue.ini configuration file.

[[kerberos]] 
# Path to Hue's Kerberos keytab file
hue_keytab=/etc/security/keytabs/hue.service.keytab 
# Kerberos principal name for Hue 
hue_principal=hue/$FQDN@EXAMPLE.COM

Set the path to the kinit based on the OS.

# Path to kinit 
# For RHEL/CentOS 5.x, kinit_path is /usr/kerberos/bin/kinit 
# For RHEL/CentOS 6.x, kinit_path is /usr/bin/kinit
kinit_path=/usr/kerberos/bin/kinit 

Set security_enabled=true for every component in hue.ini.

[[hdfs_clusters]], [[yarn_clusters]], [[liboozie]], [[hcatalog]]

Save the hue.ini file.

Restart Hue:

# /etc/init.d/hue start
