>                 Key: HADOOP-14000
>                 URL: https://issues.apache.org/jira/browse/HADOOP-14000
>             Project: Hadoop Common
>          Issue Type: Sub-task
>          Components: fs/s3
>    Affects Versions: HADOOP-13345
>            Reporter: Steve Loughran
> 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
