Я работал некоторое время с API aws java с не так много проблем. В настоящее время я использую версию библиотеки 1.5.2.
Когда я повторяю объекты внутри папки со следующим кодом:
AmazonS3 s3 = new AmazonS3Client(new PropertiesCredentials(MyClass.class.getResourceAsStream("AwsCredentials.properties")));
String s3Key = "folder1/folder2";
String bucketName = Constantes.S3_BUCKET;
String key = s3Key +"/input_chopped/";
ObjectListing current = s3.listObjects(new ListObjectsRequest()
.withBucketName(bucketName)
.withPrefix(key));
boolean siguiente = true;
while (siguiente) {
siguiente &= current.isTruncated();
contador += current.getObjectSummaries().size();
for (S3ObjectSummary objectSummary : current.getObjectSummaries()) {
S3Object object = s3.getObject(new GetObjectRequest(bucketName, objectSummary.getKey()));
System.out.println(object.getKey());
}
current=s3.listNextBatchOfObjects(current);
}
Gist: Ссылка: https://gist.github.com/fgblanch/6038699 Я получаю следующее исключение:

Caught an AmazonClientException, which means the client encountered a serious internal problem while trying to communicate with S3, such as not being able to access the network.
Error Message: Unable to execute HTTP request: Timeout waiting for connection from pool
Любая идея, как избежать этой ошибки. Это происходит только в папках с несколькими объектами, в этом случае внутри них было 463 файла. Благодаря
