---------------------------------------
Summary: s3a to instrument duration of HTTP calls
Key: HADOOP-13845
URL: https://issues.apache.org/jira/browse/HADOOP-13845
Project: Hadoop Common
Issue Type: Sub-task
Components: fs/s3
Affects Versions: 2.9.0
Reporter: Steve Loughran
HADOOP-13844 proposes pulling out the swift duration classes for reuse; this
patch proposes instrumenting s3a with it.
One interesting question: what to do with the values. For now, they could just
be printed, but it might be interesting to include in FS stats collected at the
end of a run. However, those are all assumed to be simple counters where
merging is a matter of addition. These are more metrics
