3.3. 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.
Install the connector.
RHEL/CentOS/Oracle Linux
yum install postgresql-jdbc
SLES
zypper install -y postgresql-jdbc
UBUNTU
apt-get install -y postgresql-jdbc
DEBIAN
apt-get install -y postgresql-jdbc
Confirm that .jar is in the Java share directory.
ls /usr/share/java/postgresql-jdbc.jar
Change the access mode of the .jar file to 644.
chmod 644 /usr/share/java/postgresql-jdbc.jar
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.
