如何在Scala中本地读取HDFS中的文本文件(不使用Spark)？

import org.apache.hadoop.conf.Configuration
import org.apache.hadoop.fs.{FileSystem, Path}

object HDFSFileReader {
  def main(args: Array[String]): Unit = {
    val conf = new Configuration()
    val hdfs = FileSystem.get(conf)

    val filePath = new Path("hdfs://<HDFS地址>/<文件路径>")
    val inputStream = hdfs.open(filePath)

    try {
      val content = scala.io.Source.fromInputStream(inputStream).mkString
      println(content)
    } finally {
      inputStream.close()
      hdfs.close()
    }
  }
}
