Pentaho DI无法连接到AWS Redshift - Amazon Error 100021

Question

Referring to Pentaho's Doc , we should be using RedshiftJDBC4.jar instead of version 4.1. I have downloaded the driver and placed it in the lib/ directory. Relaunched spoon.sh and I noticed it is no longer complaining about not able to find the com.amazon.redshift.jdbc4 class driver as I was using the 4.1 driver earlier. However, it still could not establish the connection.

Error connecting to database [aws_redshift] : org.pentaho.di.core.exception.KettleDatabaseException: Error occurred while trying to connect to the database

Error connecting to database: (using class com.amazon.redshift.jdbc4.Driver) Amazon Error setting default driver property values.

Can anyone help on this?

On the flip side, I can connect to my endpoint using SQLWorkbench/J, a SQL client tool.

Answer 1

Somehow I managed to get it working. It seems that downloading AWS Redshift drivers version 4, 4.1, or 4.2 and placing them in the lib/ directory did not work for me for each version by choosing Redshift as connection type (in Database Connection setup).

Instead, I chose PostgreSQL using JDBC. In host name field, I included the endpoint WITHOUT port number 5439 at the end. So, the endpoint should just end with ...amazonaws.com. Fill in database name, port number of 5439, and username and password. If this did not work, try downloading the latest PostgreSQL JDBC driver and placing it in lib/ directory and try again.
