Python MySQL Spark (java.lang.ClassNotFoundException: com.mysql.jdbc.Driver)

Question

I'm trying to use PySpark but I'm facing the following issue. I don't really understand the problem but it seems that my computer can't find the "com.mysql.jdbc.Driver" driver. I'm using a Mac OS, so I've downloaded the '.pkg' MySQL connector on https://dev.mysql.com/downloads/connector/python/ and then I installed it. However it still doesn't work and I get the following error.

Py4JJavaError: An error occurred while calling o36.load.

My python code is the following:

dataframe_mysql = sqlContext.read.format("jdbc").options(
url ="jdbc:mysql://XXXXXXXXX:PWDDDDDD@XXXXXXXXJDDD/"+newDatabaseName,
driver="com.mysql.jdbc.Driver",
dbtable="Scores",
user="XXXXXXXXX",
password="PWDDDDDD"
).load()

Having the MySQL Connector/Python doesn't help, because it needs to have MySQL Connector/J. — Mark Rotteveel, Oct 26 '19 at 18:04

but i want to run a script using Spyder – mike.depetriconi Oct 26 '19 at 16:07
'PYTHONSTARTUP=/path/to/script/below' inside the project's properties section. Add Spark submit option here DRIVER_JAVA_OPTIONS = "'" + DRIVER_JAVA_OPTIONS + "'" PYSPARK_SUBMIT_ARGS = ' --master ' + MASTER # Remember to set MASTER on UNIX CLI or in the IDE! PYSPARK_SUBMIT_ARGS += ' --driver-java-options ' + DRIVER_JAVA_OPTIONS # Built above. – Hassan Ali Oct 26 '19 at 18:33
