Description

While the <src> specified for FsShell -getmerge is not a directory,the command does nothing and there's no any message explaining the issue.
Furthermore,the exitCode is zero.

$ hdfs dfs -getmerge /user/hadoop/testfile /work/tmp/testfile
$ echo $?
0
$ ls /work/tmp/testfile
ls: cannot access /work/tmp/testfile: No such file or directory
