Allen Wittenauer commented on YARN-3170:
----------------------------------------
{code}
and job scheduling/monitoring,
{code}
Unnecessary comma.
{code}
The Scheduler has a pluggable policy plug-in,
{code}
Awkward phrasing. Unnecessary comma.
{code}
In the first version, only memory is supported.
{code}
Remove. It isn't true anymore and highlights one of the things I absolutely
hate about Hadoop documentation: roadmaps don't belong here.
{code}
The current MapReduce schedulers such as the CapacityScheduler and the
FairScheduler would be some examples of the plug-in.
{code}
"MapReduce" should be removed. "of plug-ins"; no the & make it plural. Also
link to their respective documentation pages.
{code}
The CapacityScheduler supports hierarchical queues to allow for more
predictable sharing of cluster resources
{code}
Drop this sentence.

> 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.
