hadoop fs -stat '{glob}' gives null with combo of absolute and non-existent files
---------------------------------------------------------------------------------

                 Key: HADOOP-7464
                 URL: https://issues.apache.org/jira/browse/HADOOP-7464
             Project: Hadoop Common
          Issue Type: Bug
          Components: fs
    Affects Versions: 0.20.2
         Environment: CDH3u0
            Reporter: Jay Hacker
            Priority: Minor


I'm trying to {{hadoop fs -stat}} a list of HDFS files all at once, because doing them one at a time is slow.  stat doesn't accept multiple arguments, so I'm using a glob of the form '{file1,file2}' (quoted from the shell).  I've discovered this doesn't work for me because the glob expands non-existent files to nothing, and I get nothing back from stat.  It would be nice to be able to use stat for this, but perhaps that's more of a feature request.

However, in the process, I discovered that with relative pathnames, I get back the stats for the existing files.  With absolute filenames, I get back {{stat: null}}.  


$ hadoop fs -touchz file1 file2
$ hadoop fs -stat '{file1,file2}'

$ hadoop fs -stat '{file1,file2,nonexistent}'
2011-07-15 21:21:19
2011-07-15 21:21:19
$ hadoop fs -stat '{/user/me/file1,/user/me/file2}'
2011-07-15 21:21:19
2011-07-15 21:21:19
$ hadoop fs -stat '{/user/me/file1,/user/me/file2,nonexistent}'
stat: null


Perhaps I'm doing something dumb, but it seems like stat should give the same results whether you use relative or absolute paths.
