------------------------------------------
+1 looks good to me.

> MutableGaugeInt incremented as {{allocatedGB.incr(res.getMemory() / GB *
> containers);}}
> Setting yarn.scheduler.capacity.minimum-allocation-mb to 1536 - each
> increment is counted as 1GB.
> Trying to analyze the metrics - looks like the cluster is never over 67-68%
> utilized, depending on high ram requests.
