Release Note: (was: Resolved this with HADOOP-15999 : fix for OOB
operations.)
> S3Guard: make short-circuit getFileStatus() configurable
> --------------------------------------------------------
>
> Key: HADOOP-14468
> URL: https://issues.apache.org/jira/browse/HADOOP-14468
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.0.0-beta1
> Reporter: Aaron Fabbri
> Assignee: Gabor Bota
> Priority: Minor
>
> Currently, when S3Guard is enabled, getFileStatus() will skip S3 if it gets a
> result from the MetadataStore (e.g. dynamodb) first.
> I would like to add a new parameter
> {{fs.s3a.metadatastore.getfilestatus.authoritative}} which, when true, keeps
> the current behavior. When false, S3AFileSystem will check both S3 and the
> MetadataStore.
> I'm not sure yet if we want to have this behavior the same for all callers of
> getFileStatus(), or if we only want to check both S3 and MetadataStore for
> some internal callers such as open().
