> audit/tune s3a authoritative flag in s3guard DDB Table
> ------------------------------------------------------
>
> Key: HADOOP-16697
> URL: https://issues.apache.org/jira/browse/HADOOP-16697
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.3.0
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Major
> Fix For: 3.3.0
>
>
> S3A auth mode can cause confusion in deployments, because people expect there
> never to be any HTTP requests to S3 in a path marked as authoritative.
> This is *not* the case when S3Guard doesn't have an entry for the path in the
> table. Which is the state it is in when the directory was populated using
> different tools (e.g AWS s3 command).
> Proposed
> 1. HADOOP-16684 to give more diagnostics about the bucket
> 2. add an audit command to take a path and verify that it is marked in
> dynamoDB as authoritative *all the way down*
> This command is designed to be executed from the commandline and will return
> different error codes based on different situations
> * path isn't guarded
> * path is not authoritative in s3a settings (dir, path)
> * path not known in table: use the 404/44 response
> * path contains 1+ dir entry which is non-auth
> 3. Use this audit after some of the bulk rename, delete, import, commit
> (soon: upload, copy) operations to verify that's where appropriate, we do
> update the directories. Particularly for incremental rename() where I have
> long suspected we may have to do more there.
> 4. Review documentation and make it clear what is needed (import) after
> uploading/Generating Data through other tools.
> I'm going to pull in the open JIRAs on this topic as they are all related
