> DatanodeProtocol#sendHeartbeat() returns DatanodeCommand[]. This jira proposes changing it to to return HeartbeatResponse that has DatanodeCommand[]. This allows adding other information that can be returned by the namenode to the datanode, instead of having to only return DatanodeCommand[]. For relevant discussion see HDFS-1972.
