hi,
I am trying to connect to a mysql database on my machine.
But, I am getting some error
dataframe_mysql = sqlContext.read.format("jdbc").options(
url="jdbc:mysql://localhost:3306/my_db",
driver = "com.mysql.jdbc.Driver",
dbtable = "data1",
user="123").load()
below is the full trace -
---------------------------------------------------------------------------Py4JJavaError
