In nutshell the doc to b eupdated with:
```
// Function to upload small files using putObject with content length
private def uploadSmallFileToS3(contentLength: Long): Future[_] = {
val hdfsSource: Source[ByteString, _] = streamHDFSFile
// Define the S3 putObject with content length
val s3Headers = S3Headers.empty
val s3PutObject = S3.putObject(
bucket,
bucketKey,
hdfsSource,
contentLength,
ContentTypes.`application/octet-stream`,
s3Headers
)
// Run the stream to upload the file using putObject
s3PutObject.runWith(Sink.head).flatMap(objectMetadata => {
println(s"Uploaded successfully with ETag: ${objectMetadata.eTag}")
Future.successful(Done)
})
}
```
application.conf (src/resource)
```
s3 {
region = "us-west-2"
endpoint = ""
credentials {
access-key-id = ""
secret-access-key = ""
}
# very important else bucket discovery fails.
path-style-access = true
marker {
bucket = ${S3_MARKER_BUCKET}
}
sink {
bucket = ""
}
ssl-enabled = true
}
