> Might be an unlikely scenario, but if users copyFromLocal a file/dir from local to HDFS
and want the file/dir to be renamed to _.snapshot_, then they'll see an Input/output error
 like the following:
> {code}
> schu-mbp:~ schu$ hdfs dfs -copyFromLocal testFile1 /tmp/.snapshot
> copyFromLocal: rename `/tmp/.snapshot._COPYING_' to `/tmp/.snapshot': Input/output error
> {code}
> It'd be more clear if the error output was the usual _".snapshot" is a reserved name_
(this does show in the NN logs, though).
