Ho lavorato per un po 'di tempo con aws java API con non tanti problemi. Attualmente sto usando la versione 1.5.2 della libreria."ConnectionPoolTimeoutException" durante l'iterazione di oggetti in S3
Quando sto iterazione gli oggetti all'interno di una cartella con il seguente codice:
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);
}

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
Qualsiasi idea di come per evitare questo errore. Succede solo in cartelle con un numero di oggetti, in questo caso all'interno c'erano 463 file. Grazie
