[jira] [Created] (HDFS-16234) Improve DataNodeMetrics to initialize IBR more reasonable

JiangHua Zhu created HDFS-16234:
-----------------------------------

             Summary: Improve DataNodeMetrics to initialize IBR more reasonable
                 Key: HDFS-16234
                 URL: https://issues.apache.org/jira/browse/HDFS-16234
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: datanode
            Reporter: JiangHua Zhu


DataNode performs DataNodeMetrics to initialize IBR once before sending IBR, so there may be data deviation. It should be processed after sending the IBR to the NameNode. This seems more reasonable.
