Learn about the CDP specific setup steps required before you can deploy the Debezium PostgreSQL Source connector.

In CDP, before deploying an instance of the Debezium PostgreSQL Source connector, you must download and deploy the PostgreSQL JDBC driver on all Kafka Connect hosts. Otherwise, you will not be able to deploy the connector. The following list of steps walks you through this process.

For more information regarding how the Debezium PostgreSQL connector works as well as its configuration and properties, see the Debezium connector for PostgreSQL in the Debezium documentation.

Download the PostgreSQL JDBC driver.
The JDBC driver can be downloaded from Maven Central. Cloudera recommends that you use version 42.2.24.
Copy and rename the driver to the location specified in the JDBC Driver Jars Path For Debezium Kafka property.
The default location is /var/lib/kafka_connect_jdbc. The JDBC driver must be renamed to postgresql-connector-java.jar. For example:
```
cp ./postgresql-[***VERSION***].jar /var/lib/kafka_connect_jdbc/postgresql-connector-java.jar
```

Set correct file permissions. For example:

chmod 644 /var/lib/kafka_connect_jdbc/postgresql-connector-java.jar
