Using Oozie with PostgreSQL

To set up PostgreSQL for use with Oozie:

On the Ambari Server host, stage the appropriate PostgreSQL connector for later deployment.
1. Install the connector.
  RHEL/CentOS/Oracle Linux
  yum install postgresql-jdbc
  SLES
  zypper install -y postgresql-jdbc
  Debian/Ubuntu
  apt-get install -y libpostgresql-jdbc-java
2. Confirm that .jar is in the Java share directory.
  ls /usr/share/java/postgresql-jdbc.jar
3. Change the access mode of the .jar file to 644.
  chmod 644 /usr/share/java/postgresql-jdbc.jar
4. Execute the following command:
  ambari-server setup --jdbc-db=postgres --jdbc-driver=/usr/share/java/postgresql-jdbc.jar
Create a user for Oozie and grant it permissions.
- Using the PostgreSQL database admin utility:
  echo "CREATE DATABASE <OOZIEDATABASE>;" | psql -U postgres
  echo "CREATE USER <OOZIEUSER> WITH PASSWORD '<OOZIEPASSWORD>';" | psql -U postgres
  echo "GRANT ALL PRIVILEGES ON DATABASE <OOZIEDATABASE> TO <OOZIEUSER>;" | psql -U postgres
- Where <OOZIEUSER> is the Oozie user name, <OOZIEPASSWORD> is the Oozie user password and <OOZIEDATABASE> is the Oozie database name.
