在使用IntelliJ的Scala-Spark中,您可以添加以下依赖项来在S3中获取txt文件:
libraryDependencies += "org.apache.hadoop" % "hadoop-aws" % "3.3.1"
libraryDependencies += "software.amazon.awssdk" % "s3" % "2.17.11"
import org.apache.hadoop.fs.{FileSystem, Path}
import software.amazon.awssdk.auth.credentials.{AwsBasicCredentials, StaticCredentialsProvider}
import software.amazon.awssdk.regions.Region
import software.amazon.awssdk.services.s3.{S3Client, S3Configuration}
val accessKeyId = "YOUR_ACCESS_KEY"
val secretAccessKey = "YOUR_SECRET_ACCESS_KEY"
val region = Region.US_EAST_1
val bucketName = "YOUR_BUCKET_NAME"
val filePath = "s3a://YOUR_BUCKET_NAME/path/to/file.txt"
val credentials = AwsBasicCredentials.create(accessKeyId, secretAccessKey)
val client = S3Client.builder()
.credentialsProvider(StaticCredentialsProvider.create(credentials))
.region(region)
.serviceConfiguration(S3Configuration.builder().pathStyleAccessEnabled(true).build())
.build()
val fs = FileSystem.get(client.hadoopConfiguration())
val file = fs.open(new Path(filePath))
val content = scala.io.Source.fromInputStream(file).mkString
println(content)
file.close()
client.close()
请将上述代码中的"YOUR_ACCESS_KEY"、"YOUR_SECRET_ACCESS_KEY"、"YOUR_BUCKET_NAME"和"path/to/file.txt"替换为您自己的实际值。
上述代码使用了Apache Hadoop和AWS SDK for Java,通过S3Client连接到S3存储桶,并通过FileSystem打开并读取指定的txt文件。最后,将文件内容打印到控制台。
