Varun Vasudev commented on YARN-2422:
-------------------------------------
I agree with [~sandyr] on deriving the value.
> yarn.scheduler.maximum-allocation-mb should not be hard-coded in
> yarn-default.xml

> Cluster with 40Gb NM refuses to run containers >8Gb.
> It was finally tracked down to yarn-default.xml hard-coding it to 8Gb.
> In case of lack of a better override, it should default to -
> ${yarn.nodemanager.resource.memory-mb} instead of a hard-coded 8Gb.
