Install PostgreSQL 8.4.x or 9.0.x.

Create the Oozie User and Oozie Database

For example, using the PostgreSQL psql command-line tool:

$ psql -U postgres
Password for user postgres: *****

postgres=# CREATE ROLE oozie LOGIN ENCRYPTED PASSWORD 'oozie' 
 NOSUPERUSER INHERIT CREATEDB NOCREATEROLE;
CREATE ROLE

postgres=# CREATE DATABASE "oozie" WITH OWNER = oozie
 ENCODING = 'UTF8'
 TABLESPACE = pg_default
 LC_COLLATE = 'en_US.UTF-8'
 LC_CTYPE = 'en_US.UTF-8'
 CONNECTION LIMIT = -1;
CREATE DATABASE

postgres=# \q

Configure PostgreSQL to Accept Network Connections for the Oozie User

1. Edit the postgresql.conf file and set the listen_addresses property to *, to make sure that the PostgreSQL server starts listening on all your network interfaces. Also make sure that the standard_conforming_strings property is set to off.
2. Edit the PostgreSQL data/pg_hba.conf file as follows:

   host    oozie         oozie         0.0.0.0/0             md5

Reload the PostgreSQL Configuration

$ sudo -u postgres pg_ctl reload -s -D /opt/PostgreSQL/8.4/data

Install and Start MariaDB 5.5

See MariaDB Database.

Create the Oozie Database and Oozie MariaDB User

For example, using the MariaDB mysql command-line tool:

$ mysql -u root -p
Enter password: ******

mysql> create database oozie;
Query OK, 1 row affected (0.03 sec)

mysql>  grant all privileges on oozie.* to 'oozie'@'localhost' identified by 'oozie';
Query OK, 0 rows affected (0.03 sec)

mysql>  grant all privileges on oozie.* to 'oozie'@'%' identified by 'oozie';
Query OK, 0 rows affected (0.03 sec)

mysql> exit
Bye

Add the MariaDB JDBC Driver JAR to Oozie

Cloudera recommends that you use the MySQL JDBC driver for MariaDB. Copy or symbolically link the MySQL JDBC driver JAR to the /var/lib/oozie/ directory.

  Note: You must manually download the MySQL JDBC driver JAR file.

Install and Start MySQL 5.x

Create the Oozie Database and Oozie MySQL User

For example, using the MySQL mysql command-line tool:

$ mysql -u root -p
Enter password: ******

mysql> create database oozie;
Query OK, 1 row affected (0.03 sec)

mysql>  grant all privileges on oozie.* to 'oozie'@'localhost' identified by 'oozie';
Query OK, 0 rows affected (0.03 sec)

mysql>  grant all privileges on oozie.* to 'oozie'@'%' identified by 'oozie';
Query OK, 0 rows affected (0.03 sec)

mysql> exit
Bye

Add the MySQL JDBC Driver JAR to Oozie

Copy or symbolically link the MySQL JDBC driver JAR into one of the following directories:

• For installations that use packages: /var/lib/oozie/
• For installations that use parcels: /opt/cloudera/parcels/CDH/lib/oozie/lib/

directory.

  Note: You must manually download the MySQL JDBC driver JAR file.

Install and Start Oracle 11g

Use Oracle's instructions.

Create the Oozie Oracle User and Grant Privileges

The following example uses the Oracle sqlplus command-line tool, and shows the privileges Cloudera recommends.

$ sqlplus system@localhost

Enter password: ******

SQL> create user oozie identified by oozie default tablespace users temporary tablespace temp;

User created.

SQL> grant alter any index to oozie;
grant alter any table to oozie;
grant alter database link to oozie;
grant create any index to oozie;
grant create any sequence to oozie;
grant create database link to oozie;
grant create session to oozie;
grant create table to oozie;
grant drop any sequence to oozie;
grant select any dictionary to oozie;
grant drop any table to oozie;
grant create procedure to oozie;
grant create trigger to oozie;

SQL> exit

$

  Important:

Do not make the following grant:

grant select any table;

Add the Oracle JDBC Driver JAR to Oozie

Copy or symbolically link the Oracle JDBC driver JAR into the /var/lib/oozie/ directory.

  Note: You must manually download the Oracle JDBC driver JAR file.
