Andy Isaacson commented on HADOOP-8386:
---
The Gnu Autoconf manual has this to say:
http://www.gnu.org/software/autoconf/manual/autoconf-2.67/html_node/Special-Shell-Variables.html
{quote}
CDPATH
When this variable is set it specifies a list of directories to search when
invoking cd with a relative file name that did not start with ‘./’ or ‘../’.
Posix 1003.1-2001 says that if a nonempty directory name from CDPATH is used
successfully, cd prints the resulting absolute file name. Unfortunately this
output can break idioms like ‘abs=`cd src pwd`’ because abs receives the
name twice. Also, many shells do not conform to this part of Posix; for
example, zsh prints the result only if a directory name other than . was chosen
from CDPATH.
In practice the shells that have this problem also support unset, so you
can work around the problem as follows:
(unset CDPATH) /dev/null 21 unset CDPATH
You can also avoid output by ensuring that your directory name is absolute
or anchored at ‘./’, as in ‘abs=`cd ./src pwd`’.
{quote}
So the Bash behavior is specified by Posix, alas. It is specified to write to
stdout not stderr, so the patch is correct in that regard (I was concerned we
might also need {{21}} or similar).
So, LGTM. I'll upload a patch that conforms to test-patch expectations. Thanks
for the contribution, Christopher!

If it's not an alias, cd hackery almost always is done using a shell function.
Also, a /bin/cd command cannot work -- running it would fork a child process,
change directory of the child process, and then exit, having no impact on the
parent shell process.
To figure out what your cd is doing, in bash use type cd.
{noformat}
# first, define a function foo
$ foo() { echo bar; }
# now, run it
$ foo
bar
$ type foo
foo is a function
foo ()
{
echo bar
}
$
{noformat}
In dash, {{type}} just says {{foo is a shell function}}. I bet the original
user is using bash though.
bq. Fixes the 'hadoop' script to work on Ubuntu distro and others where the
'cd' command prints to stdout
My ubuntu 12.04 install doesn't have any aliases or functions defined for cd,
can you find out what package is installing the evil settings in
/etc/bash_completion.d (most likely) and file an upstream bug?
{code}
ubuntu@ubu-cdh-0:~$ type cd
cd is a shell builtin
{code}
hadoop script doesn't work if 'cd' prints to stdout (default behavior in
Ubuntu)
Key: HADOOP-8386
URL: https://issues.apache.org/jira/browse/HADOOP-8386
Project: Hadoop Common
Issue Type: Bug
Components: scripts
Affects Versions: 1.0.2
Environment: Ubuntu
Reporter: Christopher Berner
Attachments: hadoop.diff
if the 'hadoop' script is run as 'bin/hadoop' on a distro where the 'cd'
command prints to stdout, the script will fail due to this line: 'bin=`cd
$bin; pwd`'
Workaround: execute from the bin/ directory as './hadoop'
Fix: change that line to 'bin=`cd $bin /dev/null; pwd`'

This only happens when you have the CDPATH environment variable set, and is the same issue noticed by the GIT team (http://lists-archives.com/git/623754-installation-failure-caused-by-cdpath-environment-variable.html).

We try to make sure the hadoop script runs as a bash script (via a shebang…), and rely on bash's default cd behavior to not cause this. Perhaps some environment specific item on your desktop has overriden the default behavior? The cd builtin of bash does not print, nor has an option to do so (has -L and -P AFAIK, but neither enforces such a behavior). Must be some odd function wrapper, you can probably detect via which cd or type cd?
