> Great, thanks so much @steveloughran !
thank you for finding/fixing an obscure bug.
Incidentally, if you are hanging on to streams for a long time. the `unbuffer()` method will release the stream and push out the current statistics to the FileSystem stats; this is how Impala manages long-lived streams

> [https://forums.aws.amazon.com/thread.jspa?threadID=83326], we got a solution that has helped us, would like to put the fix to the community version.
> The problem is that S3AInputStream had a short-lived S3Object which is used to create the wrappedSteam, and this object got garbage collected at random time, which caused the stream to be closed, thus the symptoms reported.
> [https://github.com/aws/aws-sdk-java/blob/1.11.295/aws-java-sdk-s3/src/main/java/com/amazonaws/services/s3/model/S3Object.java#L225] is the s3 code that closes the stream when S3 object is garbage collected:
> Here is the code in S3AInputStream that creates temporary S3Object and uses it to create the wrappedStream:
> {code:java}
> S3Object object = Invoker.once(text, uri,
> () -> client.getObject(request));
> changeTracker.processResponse(object, operation,
> targetPos);
> wrappedStream = object.getObjectContent();
