> 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
> Priority: Major
> Attachments: HDFS-15000.001.patch
>
>
> 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.
