Rob Weltman commented on HADOOP-3479:
-------------------------------------

Pretty-printing tools may be nice but do not replace proper structure in the 
document itself, especially if it is going to be edited with an off-the-shelf 
tool (XML editor or text editor) or viewed with an off-the-shelf tool (HTML 
browser, for example).

I really don't see any advantage to the generic name-value structure over one 
that reflects the semantics of the content. If it is a matter of this release 
or the next one and the decision is time-based, it could be that hierarchical 
organization has to slip to the next release. There is a risk that initial 
decisions stick, though. It isn't necessarily the case that "there will always 
be time to redo this later".

If the proposal is to switch to hierarchical structure when HADOOP-3579 is 
addressed, maybe that is the right compromise.
