Christopher Berner commented on HADOOP-8386:
--------------------------------------------
I didn't run into any other scripts that had this issue, but yes it would need
to be handled everywhere as far as I can tell. I think another option (besides
explicitly ignoring the output) would be to just add "unset CDPATH" at the
beginning of the script. I've used that in scripts that had issues with
environment variables before, and it works just fine.
> hadoop script doesn't work if 'cd' prints to stdout (default behavior in
> Ubuntu)

> 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`'
