Junping Du commented on YARN-291:
---------------------------------
Divide patch into 4 patches (01 - 04) for easily review:
- 01 patch is most Heartbeat and scheduler changes
- 02 patch is JMX implementation on NodeManager for set/get node's resource
- 03 patch is add interface through ClientRMProtocol to set node's resource
- 04 patch is add CLI based on ClientRMProtocol to get/set node's resource.
Please note that 01 can work independent with 02, or 03 and 04 (need to remove
heartbeat change).
I will add more unit tests in each sub-patch later.

> The current Hadoop YARN resource management logic assumes per node resource
> is static during the lifetime of the NM process. Allowing run-time
> configuration on per node resource will give us finer granularity of resource
> elasticity. This allows Hadoop workloads to coexist with other workloads on
> the same hardware efficiently, whether or not the environment is virtualized.
> About more background and design details, please refer: HADOOP-9165.
