I have working JDBC connection to data bricks server in Java code.
 
I'm trying to make similar connection in my JMeter project (tried with apache-jmeter-5.3 and apache-jmeter-5.4.3) using same connection details. 

I put SparkJDBC42.jar in JMeter lib (downloaded from https://databricks.com/spark/jdbc-drivers-download). 

To connect I've used `com.simba.spark.jdbc.Driver` class.
 
In Database Url using  `jdbc:spark://adb-...`

I've tried:

 - using UID and PWD inside Url
 - using UID and PWD in Username and Password fields
 - using UID and PWD in Connection Properties. 


No matter what I do, I keep getting error: 
```
"Response message:java.sql.SQLException: Cannot create JDBC driver of class 'com.simba.spark.jdbc.Driver' for connect URL ..."
```
I followed instructions from this post last response: https://stackoverflow.com/questions/66913893/how-can-i-connect-jmeter-with-databricks-spark-cluster

What can be the issue?
