Aiphago created HDFS-15382:
------------------------------

             Summary: Split DataNode FsDatasetImpl lock to blockpool volume lock 
                 Key: HDFS-15382
                 URL: https://issues.apache.org/jira/browse/HDFS-15382
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Aiphago
            Assignee: Aiphago


In HDFS-15180 we split lock to blockpool grain size.But when one volume is in heavy load and will block other request which in same blockpool but different volume.So we split lock to two leval to avoid this happend.And to improve datanode performance.
