HUE Lab: Authenticate using Linux users/groups

[ag35]

1. Make sure MySQL is prepared for Hue:
   show global VARIABLES like 'sql_mode';

Set it if empty:
mysql> set global sql_mode=STRICT_ALL_TABLES;
Query OK, 0 rows affected (0.00 sec)

Add to /etc/my.cnf file under [mysqld] so that it will stay during next restart

1. Add Oozie service to cluster, install it
2. Add hue next
3. Add HttpFs role to HDFS (if not added before), make sure Hue is pointed to HttpFs and restart the services

Stuck!!! While trying to export linux users into HUE

export JAVA_HOME=/usr/java/jdk1.7.0_67-cloudera/
/opt/cloudera/parcels/CDH/lib/hue/build/env/bin/hue useradmin_sync_with_unix
subprocess.CalledProcessError: Command '/var/run/cloudera-scm-agent/process/423-hue-HUE_SERVER/altscript.sh sec-5-password' returned non-zero exit status 1
[root@ip-172-31-56-250 423-hue-HUE_SERVER]# /var/run/cloudera-scm-agent/process/423-hue-HUE_SERVER/altscript.sh sec-5-password
Error: Password not present

export HUE_SECRET_KEY=Cloudera
/var/run/cloudera-scm-agent/process/423-hue-HUE_SERVER/altscript.sh sec-5-password

This is finally solved it!

Directory for the last Hue service startup

export HUE_CONF_DIR="/var/run/cloudera-scm-agent/process/423-hue-HUE_SERVER"
#Make sure JAVA_HOME is set, and do not get surprized....

Hue ADMIN password

export HUE_SECRET_KEY=Cloudera
#Hue Mysql database password
export HUE_DATABASE_PASSWORD=oozie
#Finally
export HUE_IGNORE_PASSWORD_SCRIPT_ERRORS=1

Finally try it

/opt/cloudera/parcels/CDH/lib/hue/build/env/bin/hue useradmin_sync_with_unix
