如何使用Spark将输出写为现有HDFS目录下的单独文件？

import org.apache.spark.SparkConf
import org.apache.spark.sql.SparkSession

val sparkConf = new SparkConf().setAppName("SparkHDFSWrite").setMaster("local")
val spark = SparkSession.builder().config(sparkConf).getOrCreate()

val data = spark.read.textFile("hdfs://<HDFS路径>")
// 进行数据处理和转换操作
val processedData = data.map(...)

processedData.write.mode("overwrite").text("hdfs://<HDFS目录>/<文件名>")

import org.apache.spark.SparkConf
import org.apache.spark.sql.SparkSession

object SparkHDFSWrite {
  def main(args: Array[String]): Unit = {
    val sparkConf = new SparkConf().setAppName("SparkHDFSWrite").setMaster("local")
    val spark = SparkSession.builder().config(sparkConf).getOrCreate()

    val data = spark.read.textFile("hdfs://<HDFS路径>")
    // 进行数据处理和转换操作
    val processedData = data.map(...)

    processedData.write.mode("overwrite").text("hdfs://<HDFS目录>/<文件名>")
  }
}
