[jira] [Updated] (HADOOP-13845) s3a to instrument duration of HTTP
calls
[ https://issues.apache.org/jira/browse/HADOOP-13845?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Steve Loughran updated HADOOP-13845:
------------------------------------
Parent Issue: HADOOP-14831 (was: HADOOP-13204)
> 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
> Priority: Minor
>
> 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
