> Current implementation of NativeS3FileSystem.java uses RetryProxy that retries exceptions that may occur on network communication with S3 API, but these exceptions must be exact instances of IOException:
> https://github.com/apache/hadoop/blob/master/hadoop-tools/hadoop-aws/src/main/java/org/apache/hadoop/fs/s3native/NativeS3FileSystem.java#L349
> Our tests show that HttpClient throws IOException subclasses which are not handled by Proxy.
> Additionally, not all methods that call S3 API are listed to be handled, i.e. storeEmptyFile and retrieveMetadata are missing.
