Andrew Wang updated HADOOP-9418:
--------------------------------

    Attachment: hadoop-9418-6.patch

Thanks Colin.

1) fixed, bigger comment

2) I think this is for performance reasons, else we'd have to resolve the 
symlink (meaning extra RTTs) each time we fetch a new batch of listings. It's 
safe though if it changes in between, {{dfs.listPaths}} will still resolve it.
                
> Add symlink resolution support to DistributedFileSystem
