Convert Dataframe to MySQL Table in Spark with Scala

// Here we are going to export dataframe content into mysql table
//we have a dataframe named "df"

scala> df.printSchema
root
 |-- address: string (nullable = true)
 |-- age: long (nullable = true)
 |-- company: string (nullable = true)
 |-- email: string (nullable = true)
 |-- gender: string (nullable = true)
 |-- id: string (nullable = true)
 |-- isActive: boolean (nullable = true)
 |-- name: string (nullable = true)
 |-- phone: string (nullable = true)


// Our dataframe has 3 records
scala> df.show
