Andrew Wang commented on HDFS-7087:
-----------------------------------
Hi Yongjun, thanks for taking a look at this. AFAIK we don't need a "-a"
option, since the HDFS shell doesn't hide paths starting with a "." like UNIXy
shells. The core issue here is that right now, FSDirectory#resolvePath doesn't
resolve "/.reserved" to anything, so we get FileNotFound when trying to do any
operations on it. Reserved paths are all very special cased right now.
I think what we need to do is create two fake FileStatuses for when people list
"/.reserved", and return those. It'd also be nice for {{getFileInfo}} on
/.reserved directly to work. I think we *shouldn't* show .reserved when listing
{{/}} though, since that could lead to bad things if someone ran e.g. a distcp
on {{/}}.

> Project: Hadoop HDFS
> Issue Type: Improvement
> Affects Versions: 2.6.0
> Reporter: Andrew Wang

> We have two special paths within /.reserved now, /.reserved/.inodes and
> /.reserved/raw. It seems like we should be able to list /.reserved to see
> them.
