Steve Loughran created HADOOP-18698:
---------------------------------------
Summary: S3ABlockOutputStream doesn't collect stats on multipart
block uploads
Key: HADOOP-18698
URL: https://issues.apache.org/jira/browse/HADOOP-18698
Project: Hadoop Common
Issue Type: Sub-task
Components: fs/s3
Affects Versions: 3.3.5
Reporter: Steve Loughran
Assignee: Steve Loughran
assertion failures in HADOOP-18695 show that S3ABlockOutputStream isn't
collecting stats on how long the individual post calls of multipart uploads:
duration or number.
that is despite some counters in the IOStatistics of the stream set up to do
this and merge to the FS in close()
Looks like the simplest fix is to instrument the FS to do collect these, rather
than in-stream. in stream would be best for context stats
