[jira] [Created] (YARN-291) Dynamic resource configuration on NM

Junping Du created YARN-291:
-------------------------------

             Summary: Dynamic resource configuration on NM
                 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


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.
