I guess the command did complete successfully since there is no error message like "No match" or "No such file or directory".

Tested -mv with 0.20.  I cannot reproduce the problem reported.

> In hadoop 0.17 & 0.18 the behavior of "hadoop dfs -mv <invalid src dir>/* <target dir>" is as shown below.
> $  hadoop dfs -mv /user/dfsload/does-not-exist/* /user/dfsload/.Trash
> hadoop: No match.
> $ echo $?
> 1
> The same command when issued to hadoop 0.20 cluster, has a "0" exit code which is incorrect.
> $  hadoop dfs -mv /user/dfsload/does-not-exist/* /user/dfsload/.Trash
> $ echo $?
> 0
> The exit code must be non-zero in this case.
