    Description

      This bug was discovered by Casey Ching.

      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:

      [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)
      ...
      

      Note that the dfs -ls output wrongly encodes the wrongly encoded directory name, turning %20 into %2520. It does the same thing with space:

      [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
