Cristina L. Abad updated HDFS-4329:
-----------------------------------
Attachment: 4329.trunk.patch
Attaching a patch for trunk. Some comments: (1) I did not do your suggested
regexp change since it would require me to strip the quotes in the result of
matcher.group(1), so it reduces some complexity in the regex and if statement
but adds complexity to remove the quotes; (2) the changes to CommandExecutor.
java and testHDFSConf.xml were straightforward, but changing PathData.java was
more complicated since this class has a fix not available in 23 to deal with
Windows paths. Due to this fix, uriToString cannot be static and thus cannot be
called from expandAsGlob. I left expandAsGlob as is, as the
getStringForChildPath change seems to be enough to fix the whitespace encoding.
The tests are passing. Should I change the 23 patch to be more similar to the
trunk patch?

> 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}
