>
> In RouterRpcServer, getListing function is handled as two parts:
> # Union all partial listings from destination ns + paths
> # Append mount points for the dir to be listed
> In the case of large dir which is bigger than DFSConfigKeys.DFS_LIST_LIMIT
> (with default value 1k), the batch listing will be used and the startAfter
> will be used to define the boundary of each batch listing. However, step 2
> here will add existing mount points, which will mess up with the boundary of
> the batch, thus making the next batch startAfter wrong.
> The initial fix is just to append the mount points when there is no more
> batch query necessary, but this will break the order of returned entries.
> Therefore more complex logic is added to make sure the order is kept. At the
> same time the remainingEntries variable inside DirectoryListing is also
> updated to include the remaining mount points.
