> URL: https://issues.apache.org/jira/browse/HADOOP-16133
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.1.2
> Reporter: Steve Loughran

>
> Applications collecting per-thread statistics from S3A get underreporting of bytes written, as all byte written in the worker call update those in a different thread.
> Proposed:
> * the bytes upload statistics are uploaded in the primary thread as a block is queued for write, not after in the completion phase in the other thread
> * final {{WriteOperationsHelper.writeSuccessful()}} takes the final statistics for its own entertainment
> Really I want context-specific storage statistics.
