Tsuyoshi Ozawa commented on YARN-3170:
--------------------------------------
[~brahmareddy], I found the last line includes the term "MRv2".
{code}
MRV2 maintains **API compatibility** with previous stable release (hadoop-1.x).
This means that all Map-Reduce jobs should still run unchanged on top of MRv2
with just a recompile.
{code}
My suggestion is as follows:
* MapReduce in hadoop-2.x maintains **API compatibility** ~
* This means that all Map-Reduce jobs should still run unchanged on top of YARN
with just a recompile.
I appreciate if you double check the reviwer's comment, though I sometimes do
mistakes :-)

> The marketing paragraph at the top, "NextGen MapReduce", etc are all
> marketing rather than actual descriptions. It also needs some general
> updates, esp given it reads as though 0.23 was just released yesterday.
