FsShell -getmerge source file pattern is broken
-----------------------------------------------

                 Key: HADOOP-6387
                 URL: https://issues.apache.org/jira/browse/HADOOP-6387
             Project: Hadoop Common
          Issue Type: Bug
          Components: fs
            Reporter: Eli Collins
             Fix For: 0.22.0


The FsShell -getmerge command doesn't work if the "source file pattern" matches files. See below. If the current behavior is intended then we should update the help documentation and java docs to match, but it would be nice if the user could specify a set of files in a directory rather than just directories.

{code}
$ hadoop fs -help getmerge
-getmerge <src> <localdst>:  Get all the files in the directories that 
		match the source file pattern and merge and sort them to only
		one file on local fs. <src> is kept.
$ hadoop fs -ls
