Steve Loughran created HADOOP-8938:
--------------------------------------

             Summary: add option to do better diags of startup configuration
                 Key: HADOOP-8938
                 URL: https://issues.apache.org/jira/browse/HADOOP-8938
             Project: Hadoop Common
          Issue Type: New Feature
          Components: bin
    Affects Versions: 2.0.2-alpha, 1.1.0
            Reporter: Steve Loughran
            Priority: Minor


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.
