Aaron T. Myers commented on HADOOP-7233:
----------------------------------------

+1, The code looks good to me.

One high-level comment: this refactor of FsShell is making a lot of changes and 
leaving a lot of TODOs in the code, all of which will be removed once the total 
refactor is completed. Since you're proceeding by piecemeal switching the 
commands over to the new system, might it make sense to do all this work in a 
branch, and then let us review the final product? It seems unfortunate to have 
transitional code in trunk over the course of this whole project, and there's 
the obvious question of what happens to the TODOs if the total refactor is 
never completed.
