---------------------------------------------------------------
You are right, it does what I described only in example 2 above and not in the
first example. When I get some more time I will think about how to avoid it in
second example as well. Something like replacing globPathLevel() with with
globStatusLevel(). btw, glob path in second example is {{/usrer/*/file}}.

> To remove the cache of FileStatus in DFSPath (HADOOP-2565) without hurting
> performance, we must use file enumeration APIs that return FileStatus[]
> rather than Path[]. Currently we have FileSystem#globPaths(), but that
> method should be deprecated and replaced with a FileSystem#globStatus().
> We need to deprecate FileSystem#globPaths() in 0.16 in order to remove the
> cache in 0.17.
