> Components: dfs, mapred
> Reporter: Arun C Murthy

> 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.)
