----------------------------------

             Summary: If the path contains '\ t' character, can not be deleted from the command
line
                 Key: HDFS-9614
                 URL: https://issues.apache.org/jira/browse/HDFS-9614

            Reporter: tangshangwen
            Assignee: tangshangwen


In our cluster, I found that some users create directory contains '\ t' 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
