>             Project: Hadoop Common
>          Issue Type: Sub-task
>          Components: fs/s3
>    Affects Versions: 3.0.0-beta1

> S3 repos can have millions of child entries
> Currently {{DirListingMetaData}} can't and {{MetadataStore.listChildren(Path path)}}
won't be able to handle directories that big, for listing, deleting or naming.
> We will need a paged response from the listing operation, something which can be iterated
over.
