Project: Hadoop HDFS
Issue Type: Sub-task
Components: data-node, name-node
Affects Versions: Federation Branch
Reporter: Suresh Srinivas
Assignee: Suresh Srinivas
Fix For: Federation Branch
Block pool storage usage needs to be sent from datanode to namenode in
heartbeat requests. This will be used by namenode to show the block pool space
usage on namenode webUI. This will also be used by Balancer eventually for
balancing block pool usage.
