Subject [jira] [Created] (HDFS-4329) DFSShell issues with directories with spaces in name
Date Thu, 20 Dec 2012 19:39:12 GMT
Andy Isaacson created HDFS-4329:
-----------------------------------

             Summary: DFSShell issues with directories with spaces in name
                 Key: HDFS-4329
                 URL: https://issues.apache.org/jira/browse/HDFS-4329
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: hdfs-client
    Affects Versions: 2.0.2-alpha
            Reporter: Andy Isaacson
            Assignee: Andy Isaacson


The command {{dfs -put /foo/hello.txt dir}} is supposed to create {{dir/hello.txt}} on HDFS.
 It doesn't work right if "dir" has a space in it:

{code}
[adi@haus01 ~]$ hdfs dfs -mkdir 'space cat'
[adi@haus01 ~]$ hdfs dfs -put /etc/motd 'space cat'
[adi@haus01 ~]$ hdfs dfs -cat 'space cat/motd'
cat: `space cat/motd': No such file or directory
[adi@haus01 ~]$ hdfs dfs -ls space\*
Found 1 items
-rw-r--r--   2 adi supergroup        251 2012-12-20 11:16 space%2520cat/motd
[adi@haus01 ~]$ hdfs dfs -cat 'space%20cat/motd'
Welcome to Ubuntu 12.04.1 LTS (GNU/Linux 3.2.0-30-generic x86_64)
...
{code}

Note that the {{dfs -ls}} output wrongly encodes the wrongly encoded directory name, turning
{{%20}} into {{%2520}}.  It does the same thing with space:
{code}
[adi@haus01 ~]$ hdfs dfs -touchz 'space cat/foo'
[adi@haus01 ~]$ hdfs dfs -ls 'space cat'
Found 1 items
-rw-r--r--   2 adi supergroup          0 2012-12-20 11:36 space%20cat/foo
{code}
