Xiaoyu Yao updated HDFS-10930:
------------------------------
Description:
Datanode IO (Disk/Network) related operations and instrumentations are
currently spilled in many classes such as DataNode.java, BlockReceiver.java,
BlockSender.java, FsDatasetImpl.java, FsVolumeImpl.java, DirectoryScanner.java,
BlockScanner.java, FsDatasetAsyncDiskService.java, LocalReplica.java,
LocalReplicaPipeline.java, Storage.java, etc.
This ticket is opened to consolidate IO related operations for easy
instrumentation, metrics collection, logging and trouble shooting.
