Subject [jira] [Created] (HDFS-4821) It's possible to create files with special characters in the filenames, but 'hadoop fs -ls' gives no indication

Stephen Fritz created HDFS-4821:
-----------------------------------

             Summary: It's possible to create files with special characters in the filenames,
but 'hadoop fs -ls' gives no indication
                 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
