> Allow authoritative mode on a subdirectory
> ------------------------------------------
>
> Key: HADOOP-16396
> URL: https://issues.apache.org/jira/browse/HADOOP-16396
> Project: Hadoop Common
> Issue Type: Improvement
> Components: fs/s3
> Reporter: Sean Mackrory
> Assignee: Sean Mackrory
> Priority: Major
> Attachments: HADOOP-16396.001.patch, HADOOP-16396.002.patch,

>
> Let's allow authoritative mode to be applied only to a subset of a bucket.
> This is coming primarily from a Hive warehousing use-case where Hive-managed
> tables can benefit from query planning, but can't speak for the rest of the
> bucket. This should be limited in scope and is not a general attempt to allow
> configuration on a per-path basis, as configuration is currently done on a
> per-process of a per-bucket basis.
> I propose a new property (we could overload
> fs.s3a.metadatastore.authoritative, but that seems likely to cause confusion
> somewhere). A string would be allowed that would then be qualified in the
> context of the FileSystem, and used to check if it is a prefix for a given
> path. If it is, we act as though authoritative mode is enabled. If not, we
> revert to the existing behavior of fs.s3a.metadatastore.authoritative (which
> in practice will probably be false, the default, if the new property is in
> use).
> Let's be clear about a few things:
> * Currently authoritative mode only short-cuts the process to avoid a
> round-trip to S3 if we know it is safe to do so. This means that even when
> authoritative mode is enabled for a bucket, if the metadata store does not
> have a complete (or "authoritative") current listing cached, authoritative
> mode still has no effect. This will still apply.
> * This will only apply to getFileStatus and listStatus, and internal calls to
> their internal counterparts. No other API is currently using authoritative
> mode to change behavior.
> * This will only apply to getFileStatus and listStatus calls INSIDE the
> configured prefix. If there is a recursvie listing on the parent of the
> configured prefix, no change in behavior will be observed.
