Siddharth Seth commented on YARN-219:
-------------------------------------

Bobby, I've posted a patch to YARN-162 which I can wrap up if you want to pull it into 0.23.5.


Otherwise, this patch looks good - one minor nit, the sleep can easily be replaced with a
wait/notify.

> The NM should only aggregate logs when the application finishes.  This will reduce the
load on the NN, especially with respect to lease renewal.
