Steve Loughran commented on HADOOP-12346:
-----------------------------------------

-1 to any changes to s3n; its used enough that changing things would only cause 
surprises. Things installed via management tooling can pick up the defaults 
from those, and the people who do the tools can therefore control what those 
defaults are. More succinctly "we don't like changing defaults, even when they 
aren't always the best"

As s3a is newer, that's probably more amenable to change, under the "getting it 
working completely" category

> Increase some default timeouts / retries for S3a connector

> I've been seeing some flakiness in jobs runnings against S3a, both first hand 
> and with other accounts, for which increasing fs.s3a.connection.timeout and 
> fs.s3a.attempts.maximum have been a reliable solution. I propose we increase 
> the defaults.
