Whoa yeah, nice catch indeed; I would never have thought of that.
It turns out that's not the issue at all, but that suggestion pointed me in the right direction. A few things to note here... Thing 1: 'which cd' doesn't help because cd is a builtin, and so you get the "which: no cd in (..." result. Thing 2: Because I typically don't use '-x' in my alias commands, the hadoop script doesn't inherit my shell aliases. I verified this by adding an 'alias -p' to the hadoop script, and the script has no aliases for anything. Thing 3: If the CDPATH environment variable exists, and the path is ambiguous, the cd command is *not* silent, aliased or not. It will print the dir it chose to cd to. In my case, there were 2 'bin' possibilities in my CDPATH. So I'm going to unset my CDPATH, since I never really make use of it for anything. I forgot it was set, and probably would have been pretty surprised when it would actually have had an effect. I know this kind of thing is incredibly difficult to accomodate, but perhaps having the hadoop scripts deal with the potential output from cd might be worthwhile.
