> HDFS-10917 added various peer performance metrics on individual DataNode. These metrics should be reported to NameNode as part of heart beat messages. In addition, NameNode should maintain the corresponding metrics but in a way of aggregation, and therefore friendly consumable by DataNode self-healing actions afterwards.
