>                 Key: HDFS-643
>                 URL: https://issues.apache.org/jira/browse/HDFS-643
>             Project: Hadoop HDFS
>          Issue Type: Bug
>    Affects Versions: 0.20.1
>            Reporter: Bryan Duxbury
> I had a very strange experience today with the bin/hadoop dfs -mv command. I accidentally
passed 3 parameters, like so:
> {code}
> bin/hadoop dfs -mv /1 /2 /3
> {code}
> My intent was to mv /1 to /3, but mis-pasted some stuff. However, to my surprise, the
result I got was that /1 had been moved to /2, and /2 had then been moved to /3! This seems
like totally confusing semantics - I would have expected a 3-parameter move to either ignore
the 3rd parameter or error out altogether. Needless to say, a solid 10 minutes of confused
scrambling commenced.
