Verify that you have the JDBC drivers to access JDBC-compliant databases in the Hadoop environment. You might need separate drivers for metadata import and for run-time processing.
Perform this task in the following situations:
You are integrating for the first time.
You download drivers based on design-time and run-time requirements:
To import metadata, you can use the DataDirect drivers packaged with the Informatica installer if they are available. If they are not available, use any Type 4 JDBC driver that the database vendor recommends.
To run mappings, use any Type 4 JDBC driver that the database vendor recommends. Some distributions support other drivers to use Sqoop connectors. You cannot use the DataDirect drivers for run-time processing.
