Date Thu, 01 Dec 2016 01:12:58 GMT

     [ https://issues.apache.org/jira/browse/HDFS-11194?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Xiaobing Zhou updated HDFS-11194:
---------------------------------
    Description: 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.  (was: 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.)
