             Summary: S3Guard: Implement access policy using metadata store as source of truth.
                 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
            Priority: Minor


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.
