Unrecognized connection property 'url' when using Presto JDBC in Spark SQL

Here is my spark sql code, where I am trying to read a presto table based on this guide;  https://spark.apache.org/docs/latest/sql-data-sources-jdbc.html

 val df = spark.read
 .format("jdbc")
 .option("driver", "com.facebook.presto.jdbc.PrestoDriver")
 .option("url", "jdbc:presto://localhost:8889/mycatalog")
 .option("query", "select * from mydb.mytable limit 1")
 .option("user", "myuserid")
 .load()

  I am getting the following exception, unrecognized connection property 'url'

Exception in thread "main" java.sql.SQLException: Unrecognized connection property 'url'

Seems like this issue is related to https://github.com/prestodb/presto/issues/9254  where the property url is not a recognized property in Presto and looks like the fix needs to be done on the Spark side? Are there any other workaround for this issue?

PS:

Spark Version: 3.1.1
presto-jdbc version: 0.245
Solution

  • There is no issue with spark or presto JDBC driver. I don't think URL which you specified will work.

    You should change that to below format.

    jdbc:presto://localhost:8889/mycatalog

    UPDATE

    Not sure how it's working with spark version < 3. As an workaround you can use another jar where strict config check has been removed as specified here.
