Hi,
I am trying to get data from mysql using JdbcRDD using code The table have
three columns
val url = "jdbc:mysql://localhost:3306/studentdata"
val username = "root"
val password = "root"
val mysqlrdd = new org.apache.spark.rdd.JdbcRDD(sc,() => {
Class.forName("com.mysql.jdbc.Driver")
DriverManager.getConnection(url, username, password)
},"SELECT * FROM student_info",
1, 20, 2, r => r.getString("studentname"))
mysqlrdd.saveAsTextFile("/home/ubuntu/mysqljdbc")
I am getting runtime error as
14/07/30 22:05:04 INFO JdbcRDD: statement fetch size set to: -2147483648 to
