Review Comment:
shouldn't this be FutureIO.class ?
> S3A: Unable to recover from failure of multipart block upload attempt "Status

> Key: HADOOP-19221
> URL: https://issues.apache.org/jira/browse/HADOOP-19221
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.4.0
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Major
> Labels: pull-request-available
>
> If a multipart PUT request fails for some reason (e.g. networrk error) then
> all subsequent retry attempts fail with a 400 Response and ErrorCode
> RequestTimeout .
> {code}
> Your socket connection to the server was not read from or written to within
> the timeout period. Idle connections will be closed. (Service: Amazon S3;
> Status Code: 400; Error Code: RequestTimeout; Request ID:; S3 Extended
> Request ID:
> {code}
> The list of supporessed exceptions contains the root cause (the initial
> failure was a 500); all retries failed to upload properly from the source
> input stream {{RequestBody.fromInputStream(fileStream, size)}}.
> Hypothesis: the mark/reset stuff doesn't work for input streams. On the v1
> sdk we would build a multipart block upload request passing in (file, offset,
> length), the way we are now doing this doesn't recover.
> probably fixable by providing our own {{ContentStreamProvider}}
> implementations for
> # file + offset + length
> # bytebuffer
> # byte array
> The sdk does have explicit support for the memory ones, but they copy the
> data blocks first. we don't want that as it would double the memory
> requirements of active blocks.
