> 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:
> {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}
