In a nutshell, this is the same problem you face with shell scripting, assuming external binary files exist. assuming they take a set of arguments, assuming they produce a result code, assuming the output is formatted in a specific way. One could add several tests and log/exit if these tests fail, or change "DrWho" to a short stringified version of the exception. Really though its one of those things that gets you the first time, second time you setup hadoop on solaris....your an expert :)
