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?
Spark Version: 3.1.1
presto-jdbc version: 0.245
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.

@odonnry is correct that the issue was fixed in spark 3.3.x, but if anyone cannot upgrade to Spark 3.3.x and is trying to use Trino, I created a workaround below according to the Jira issue linked by @Mohana
