> 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).
