> HADOOP-8468 propose network topology changes for running on virtualized
> infrastructure, which includes:
> 1. Add "NodeGroup" layer in new NetworkTopology (also known as
> NetworkTopologyWithNodeGroup): HADOOP-8469, HADOOP-8470
> 2. Update Replica Placement/Removal Policy to reflect new topology layer:
> HDFS-3498, HDFS-3601
> 3. Update balancer policy:HDFS-3495
> 4. Update Task Scheduling Policy to reflect new topology layer and support
> the case that compute nodes (NodeManager or TaskTracker) and data nodes are
> separated into different VMs, but still benefit from physical host locality:
> YARN-18, YARN-19.
> This JIRA will address the backport work on branch-1 which will be divided
> into 4 issues/patches in related jira issues.
