Connecting to a postgresql db using JDBC from the Bluemix Apache Spark service

Question

I have a problem connecting to my postgresql 8.4 db using Apache Spark service on Bluemix.

My code is:

%AddJar https://jdbc.postgresql.org/download/postgresql-8.4-703.jdbc4.jar -f
val sqlContext = new org.apache.spark.sql.SQLContext(sc)

sqlContext.load("jdbc", Map("url" -> "jdbc:postgresql://<ip_address>:5432/postgres?
user=postgres&password=<password>", "dbtable" -> "table_name"))

And I get the error:

Name: java.sql.SQLException

Message: No suitable driver found for jdbc:postgresql://:5432/postgres?user=postgres&password=

I've read around and it seems I need to add the JDBC driver to the Spark class path. I've no idea how to do this in the Bluemix Apache Spark service.

There is currently an issue with adding JDBC drivers to Bluemix Apache Spark. The team is working to resolve it. You can follow the progress here: https://developer.ibm.com/answers/questions/248803/connecting-to-postgresql-db-using-jdbc-from-bluemi.html
