> HADOOP-8931 shows a symptom of a larger problem: we need better diagnostics of what all the environment variables and settings going through the hadoop scripts to find out why something isn't working.
> Ideally some command line parameter to the scripts (or even: a new environment variable) could trigger more display of critical parameters.
