> bash-tab-completion/hadoop.sh checks that the first token in the command is an existing, executable file - which assumes that the path to the hadoop executable is specified (or that it's in the working directory). If the executable is somewhere else in PATH, tab completion will not work.
> I propose that the first token be passed through 'which' so that any executables in the path also get detected. I've tested that this technique will work in the event that relative and absolute paths are used as well.
