Redshift connection

villa_emanuel

Hi all.

 

I am using rapidminer Studio free, and I am trying to connect to Amazon Redshift, couldn't find any where for how to do this in a step by step, however I figure that I need to download a driver from amazon, which I did from this site:

http://docs.aws.amazon.com/redshift/latest/mgmt/configure-jdbc-connection.html#download-jdbc-driver

 

I was able to get it "installed" on RapidMiner Studio, however when I try to connect I get the following error:

[Amazon](500310) Invalid operation: no pg_hba.conf entry for host "an IP address", user "my user", data...

 

Trying to get around this error I found that is necessary to include two changes on the advanced variables for 

AuthMech=REQUIRE and SSL=TRUE

 

However I can't change those variables, the most I can do is change them to a question mark "?" and select the override box, but can't change any variables at all, and of course once I try to test the connection with the "?" selected I get the error of "AuthMech values should be REQUIRED... etc..."

 

Any ideas?

 

Thanks in advance.

I figured it out.

 

Actually had to use the configuration directly on the read database operator and use the define connection as "url" like the following:

jdbc:redshift://<ipaddress>:<port>/<batabase/schema>?AuthMech=REQUIRE&ssl=TRUE

 

It worked like a charm.

Hi,

 

this looks like your database connection is not fully configured and reasonable values for host, user and password are missing or for some reason are not correctly passed to Redshift. How does your configuration look like?
