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

-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
