> Key: HADOOP-13451
> URL: https://issues.apache.org/jira/browse/HADOOP-13451
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Reporter: Chris Nauroth
> Assignee: Lei (Eddy) Xu
>
> Implement an S3A access policy that provides strong consistency and improved
> performance by using the metadata store as the source of truth for metadata
> operations. In many cases, this will allow S3A to short-circuit calls to S3.
> Assuming shorter latency for calls to the metadata store compared to S3, we
> expect this will improve overall performance. With this policy, a client may
> not be capable of reading data loaded into an S3 bucket by external tools
> that don't integrate with the metadata store. Users need to be made aware of
> this limitation.
