-------------------------------
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.
