[jira] [Created] (HDFS-15000) Improve FsDatasetImpl to avoid IO operation in datasetLock

Xiaoqiao He created HDFS-15000:
----------------------------------

             Summary: Improve FsDatasetImpl to avoid IO operation in datasetLock
                 Key: HDFS-15000
                 URL: https://issues.apache.org/jira/browse/HDFS-15000
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: datanode
            Reporter: Xiaoqiao He
            Assignee: Aiphago


As HDFS-14997 mentioned, some methods in #FsDatasetImpl such as #finalizeBlock, #finalizeReplica, #createRbw includes IO operation in the datasetLock, It will block some logic when IO load is very high. We should reduce grain fineness or move IO operation out of datasetLock.
