             Summary: AmazonS3Client.deleteObjects() need to be limited to 1000 entries per call
                 Key: HADOOP-10714
                 URL: https://issues.apache.org/jira/browse/HADOOP-10714
             Project: Hadoop Common
          Issue Type: Bug
          Components: fs/s3
    Affects Versions: 2.4.0
            Reporter: David S. Wang

            Priority: Critical


In the patch for HADOOP-10400, calls to AmazonS3Client.deleteObjects() need to have the number of entries at 1000 or below. Otherwise we get a Malformed XML error similar to:

Note that this is mentioned in the AWS documentation:
http://docs.aws.amazon.com/AmazonS3/latest/API/multiobjectdeleteapi.html

"The Multi-Object Delete request contains a list of up to 1000 keys that you want to delete. In the XML, you provide the object key names, and optionally, version IDs if you want to delete a specific version of the object from a versioning-enabled bucket. For each key, Amazon S3….”
