Daniel Templeton commented on HDFS-9614:
----------------------------------------
This was actually one of the puzzlers in my Hadoop puzzlers talk. The wildcard
will not bind to special characters.
The way to delete the file is:
{{python -c 'print "/user/hadoop/tangshangwen\r"' | xargs -n 1 hdfs dfs -rm}}
> If the path contains '\r' character, can not be deleted from the command line

> In our cluster, I found that some users create directory contains '\r'
> character, cause we can not be deleted from the command line. for example
> {code:title=Test.java|borderStyle=solid}
> try {
> FileSystem fs = FileSystem.get(new Configuration());
> fs.mkdirs(new Path("/user/hadoop/tangshangwen\r"));
> IOUtils.closeQuietly(fs);
> } catch (IOException e) {
> e.printStackTrace();
> }
> {code}
> Then we delete
> {noformat}
> $ hdfs dfs -ls /user/hadoop/
