Vinod Kumar Vavilapalli commented on YARN-291:
----------------------------------------------
Interesting. Quickly read throw your doc, can you please post YARN only design
here?
- +1 for the reactive resource change to start with.
- Instead of exposing via JMX, being a fairly fundamental feature, we should
do RPC and optionally the web-services to the NM directly. And we should add
command line util too.

> Key: YARN-291
> URL: https://issues.apache.org/jira/browse/YARN-291
> Project: Hadoop YARN
> Issue Type: New Feature
> Components: nodemanager, scheduler
> Reporter: Junping Du
> Assignee: Junping Du
> Labels: features
>
> 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.
