-------------------------------------
Hi [~cheersyang]
Thanks for watching.
We found NM was killed by OOM-killer.
conditions are as follows:
```
yarn.nodemanager.resource.memory.enabled=false
yarn.nodemanager.resource.memory-mb = 100G
Physical Memory of NM machine is 120G
NM has two container, each requests 40G memory, but actual each request 50G+
```
So we thought setting limit on the hireachy of hadoop-yarn
> set memory.limit_in_bytes when NodeManager starting
