Complete the following instructions to set up Oozie configuration files:

Extract the Oozie configuration files.
From the downloaded scripts.zip file, extract the files from the configuration_files/oozie directory to a temporary directory.

Modify the configuration files.

In the temporary directory, locate the following file and modify the properties based on your environment. Search for TODO in the files for the properties to replace.

Edit the oozie-site.xml and modify the following properties:

<property>     
 <name>oozie.base.url</name>     
 <value>http://$oozie.full.hostname:11000/oozie</value>
 <description>Enter your Oozie server hostname.</description>
</property>

<property>     
 <name>oozie.service.JPAService.jdbc.url</name>     
 <value>jdbc:derby:$OOZIE_DATA_DIR/$soozie.db.schema.name-db;create=true</value>
 <description>JDBC URL
                For Derby database: jdbc:derby:$OOZIE_DATA_DIR/$soozie.db.schema.name-db;create=true
                For MySQL database: jdbc:mysql://$dbhost:3306/$dbname
                For Oracle database: jdbc:oracle:thin:@$dbhost:1521/$oozie_dbname 
                For PostgreSQL database: jdbc:postgresql://$dbhost:5432/$oozie_dbname

</property>

where $soozie.db.schema.name-db is set to oozie.

<property>     
  <name>oozie.service.JPAService.jdbc.driver</name>
     <value>org.apache.derby.jdbc.EmbeddedDriver</value>
     <description>

                 For PostgreSQL database: org.postgresql.Driver
     </description>
</property>

<property>
     <name>oozie.service.JPAService.jdbc.username</name>
     <value>$oozie_user</value>

Edit the oozie-env.sh and modify the following properties:

<property>

 <value>/var/log/oozie</value>
 <description>Use value from $OOZIE_LOG_DIR </description>
</property>

<property>     
 <name>OOZIE_PID_DIR</name>     
 <value>/var/run/oozie</value>
 <description>Use value from $OOZIE_PID_DIR </description>
</property>

<property>     
 <name>OOZIE_DATA_DIR</name>     
 <value>/var/db/oozie</value>
 <description>Use value from $OOZIE_DATA_DIR </description>
</property>

Copy the Configuration Files
On your Oozie server create the config directory, copy the config files and set the permissions:
```
rm -r $OOZIE_CONF_DIR ;
mkdir -p $OOZIE_CONF_DIR ;
```
Copy all the config files to $OOZIE_CONF_DIR directory.

Set appropriate permissions.

chown -R $OOZIE_USER:$HADOOP_GROUP $OOZIE_CONF_DIR/../ ;
chmod -R 755 $OOZIE_CONF_DIR/../ ;

where:

$OOZIE_CONF_DIR is the directory to store Oozie configuration files. For example, /etc/oozie/conf.
$OOZIE_DATA is the directory to store the Oozie data. For example, /var/db/oozie.
$OOZIE_LOG_DIR is the directory to store the Oozie logs. For example, /var/log/oozie.
$OOZIE_PID_DIR is the directory to store the Oozie process ID. For example, /var/run/oozie.
$OOZIE_TMP_DIR is the directory to store the Oozie temporary files. For example, /var/tmp/oozie.
$OOZIE_USER is the user owning the Oozie services. For example, oozie.
$HADOOP_GROUP is a common group shared by services. For example, hadoop.
