Steve Loughran resolved HADOOP-14645.
-------------------------------------
Resolution: Won't Fix
> add a predicate/option to probe an S3A FS for being consistent
> --------------------------------------------------------------
>
> Key: HADOOP-14645
> URL: https://issues.apache.org/jira/browse/HADOOP-14645
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: HADOOP-13345
> Reporter: Steve Loughran
>
> The committer work shows It's useful for s3a-aware code to be able to ask if
> the FS is consistent fir listings. AWS S3 is when s3guard is turned on, but
> third-party S3 implementations may also be consistent.
> The committer should be able to ask an FS if it is consistent, something
> which can be
> * off by default against AWS
> * configured to be one for all buckets (external s3 server)
> * dynamically set when s3guard is enabled.
> This could be done with some predicate isListingConsistent(), or just probed
> as an FS option (fs.s3a.consistent.listing) which could be set explicitly in
> configs, and set dynamically when s3guard is on. That's actually the
> simpleset route all round
