Hadoop daemons should support generic command-line options by implementing the Tool interface
---------------------------------------------------------------------------------------------

                 Key: HADOOP-2106
                 URL: https://issues.apache.org/jira/browse/HADOOP-2106
             Project: Hadoop
          Issue Type: Improvement
            Reporter: Arun C Murthy
            Assignee: Arun C Murthy
            Priority: Critical
             Fix For: 0.16.0


Hadoop daemons (NN/DN/JT/TT) should support generic command-line options (i.e. -nn / -jt/
-conf / -D) by implementing the Tool interface.

This is particularly useful for cases where the masters(NN/JT) are to be configured dynamically
e.g. via HoD.

(I suspect we will need to possibly tweak some the the hadoop scripts too, possibly.)
