Amazon-SDK(Java)のサンプルコードS3TransferProgressSample.java
を使用して、大きなファイルをAmazon-S3ストレージ(also posted here on AWS docs)にアップロードしようとしました。大きなファイルをAmazon S3にアップロードする際の問題
しかし、私は11ギガバイトのファイルをアップロードしようとしていたとき、アップロードはエラーメッセージを表示して異なるポイントで立ち往生されています
Unable to upload file to Amazon S3: Unable to upload part: Unable toexecute HTTP request: Unbuffered entity enclosing request can not be repeated " (attached screenshot).
にIOExceptionがSDKは、要求を再試行することができません発生した後、それはそのように見えます(下記参照)。
誰かがこれに遭遇しますか?これを解決するベストプラクティスは何ですか?任意のコードが評価されます。

OK、エラー時にアップロードの一部を再試行する方法をコードで指定できますか? – Alexey
@Alexey - うまくいけば正しい軌道に乗せるためにサンプルを追加しました。基本的な考え方は、アップロード全体をキャンセルするのではなく、失敗した場合にパーツを再試行することです。 –
ありがとう、これは私の問題を解決しました。良いアイデアは、高速アップロードを可能にするために複数のスレッドを使用することです。 – Alexey
