> 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.
