Junping Du updated HADOOP-8817:
-------------------------------
Description:
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.
Target Version/s: 1.0.3
