Steve Loughran created HADOOP-16133:
---------------------------------------
Summary: S3A statistic collection underrecords bytes written in
helper threads
Key: HADOOP-16133
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.
