使用dataframe scala创建文件名为时间戳的csv文件

import org.apache.spark.sql.{DataFrame, SaveMode, SparkSession}
import java.text.SimpleDateFormat
import java.util.Date

val spark = SparkSession.builder()
  .appName("Create CSV File with Timestamp")
  .getOrCreate()

val data = Seq(("John", 25), ("Alice", 30), ("Bob", 35))
val columns = Seq("Name", "Age")
val df = spark.createDataFrame(data).toDF(columns: _*)

val timestamp = new SimpleDateFormat("yyyyMMddHHmmss").format(new Date())

val filePath = s"/path/to/csv/file/$timestamp.csv"

df.write.mode(SaveMode.Overwrite)
  .option("header", "true")
  .csv(filePath)
