有人能告诉我下面的代码有什么问题吗?大文件上传(>10 me )在ResetException: Failed to reset the request input stream中总是失败吗？

失败总是发生在一段时间之后(即大约15分钟之后)，这意味着上传进程执行时只会在中间某个地方失败。

下面是我尝试调试这个问题的地方：

  1. in.marksSupported() == false // checking if mark is supported on my FileInputStream 我高度怀疑这就是问题所在，因为S3 SDK似乎想在上传过程中的某个点执行重置操作，可能是连接丢失了，或者传输过程遇到了一些错误。
  2. 将我的FileInputStream包装在BufferedInputStream中以启用标记。现在调用in.marksSupported()返回true，这意味着标记支持在那里。奇怪的是，上传过程仍然失败，同样的错误。
  3. 添加putRequest.getRequestClientOptions.setReadLimit(n)，其中n=100000 (100kb), and 800000000 (800mb)但仍然抛出相同的错误。我怀疑是因为这个参数用于重置流，正如上面所述，流在FileInputStream上不受支持。

有趣的是，在我的AWS开发帐户上没有发生同样的问题。我认为这仅仅是因为dev帐户没有像我的生产帐户那样负载很重，这意味着上传过程可以尽可能顺利地执行，而不会出现任何故障。

请看我的代码如下：

代码语言：javascript
运行
复制
object S3TransferExample {
// in main class
def main(args: Array[String]): Unit = {
    ...
    val file = new File("/mnt/10gbfile.zip")
    val in = new FileInputStream(file)
    // val in = new BufferedInputStream(new FileInputStream(file)) --> tried wrapping file inputstream in a buffered input stream, but it didn't help..
    upload("mybucket", "mykey", in, file.length, "application/zip").waitForUploadResult
    ...
}

val awsCred = new BasicAWSCredentials("access_key", "secret_key")
val s3Client = new AmazonS3Client(awsCred)
val tx = new TransferManager(s3Client)

def upload(bucketName: String,  keyName: String,  inputStream: InputStream,  contentLength: Long,  contentType: String,  serverSideEncryption: Boolean = true,  storageClass: StorageClass = StorageClass.ReducedRedundancy ):Upload = {
  val metaData = new ObjectMetadata
  metaData.setContentType(contentType)
  metaData.setContentLength(contentLength)

  if(serverSideEncryption) {
    metaData.setSSEAlgorithm(ObjectMetadata.AES_256_SERVER_SIDE_ENCRYPTION)
  }

  val putRequest = new PutObjectRequest(bucketName, keyName, inputStream, metaData)
  putRequest.setStorageClass(storageClass)
  putRequest.getRequestClientOptions.setReadLimit(100000)

  tx.upload(putRequest)
 
}
}

下面是完整的堆栈跟踪：

这看起来肯定是个bug，我已经报告了。解决方案是使用另一个构造函数，它接受File而不是InputStream

代码语言：javascript
运行
复制
def upload(bucketName: String,  keyName: String,  file: File,  contentLength: Long,  contentType: String,  serverSideEncryption: Boolean = true,  storageClass: StorageClass = StorageClass.ReducedRedundancy ):Upload = {
  val metaData = new ObjectMetadata
  metaData.setContentType(contentType)
  metaData.setContentLength(contentLength)

  if(serverSideEncryption) {
    metaData.setSSEAlgorithm(ObjectMetadata.AES_256_SERVER_SIDE_ENCRYPTION)
  }

  val putRequest = new PutObjectRequest(bucketName, keyName, file)
  putRequest.setStorageClass(storageClass)
  putRequest.getRequestClientOptions.setReadLimit(100000)
  putRequest.setMetadata(metaData)
  tx.upload(putRequest)

}
}

我调查过这个问题，说来话长。

其结论是:通过向java命令行插入以下选项，将系统属性传递给java

-Dcom.amazonaws.sdk.s3.defaultStreamBufferSize=YOUR_MAX_PUT_SIZE

请参阅https://github.com/aws/aws-sdk-java/blob/master/aws-java-sdk-s3/src/main/java/com/amazonaws/services/s3/AmazonS3Client.java#L1668

这告诉AmazonS3Client设置适当的最大不可卷缓冲区大小，这将用于重读以进行重试。
