Thomas Graves commented on MAPREDUCE-4296:
------------------------------------------
Mostly looks good. couple minor things:
* we should add new configs to the release notes.
* YarnConfiguration - the comment is wrong (+ /** Whether to enable log
aggregation */) - should be to enable log aggregation deletion service.
* I'm on the wall about the 30 minute check. In one way its nice so users
don't shoot themselves but at the same time it makes it harder to test and is
less flexible. I think in the minimum we should document that we have the 30
minute config, otherwise perhaps just remove the check and add a comment that
you shouldn't set it to low.

> It might make sense for job history server to remove them.
