Steve Loughran commented on HADOOP-15426:
-----------------------------------------
Though it means that tests can start timing out. Note also that AWS Does do its
own internal retrying, passed down from the property {{
"fs.s3a.attempts.maximum"}}. That's just all opaque to us. This extra retry is
around that; probably worth working out what is going on underneath to avoid
replicating too much. I think it may be best just to crank down the value of
{{fs.s3a.s3guard.ddb.max.retries}} to something smaller. Alternatively, shrink
the #of retry events in the AWS SDK, so we see it all, and so will our metrics.
