>                 Key: HDFS-4821
>                 URL: https://issues.apache.org/jira/browse/HDFS-4821
>             Project: Hadoop HDFS
>          Issue Type: Improvement
>          Components: hdfs-client
>            Reporter: Stephen Fritz

> For example:
> -bash-4.1$ hadoop fs -mkdir /user/hdfs
> -bash-4.1$ hadoop fs -touchz /user/hdfs/dupfile
> -bash-4.1$ hadoop fs -touchz /user/hdfs/dupfile^M
> -bash-4.1$ hadoop fs -ls /user/hdfs
> Found 2 items
> -rw-r--r--   3 hdfs supergroup          0 2013-05-14 07:13 /user/hdfs/dupfile
> -rw-r--r--   3 hdfs supergroup          0 2013-05-14 07:13 /user/hdfs/dupfile
> By way of comparison, bash will print a '?' at the end of the file name, indicating there's a special character in the filename, which isn't perfect but at least gives an indication that there's more to the filename than just alphanumeric characters
