> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 0.23.9, 2.2.0
> Reporter: Kihwal Lee

>
> After HDFS-4581 and HDFS-4699, {{checkDiskError()}} is not called when
> network errors occur during processing data node requests. This appears to
> create problems when a disk is having problems, but not failing I/O soon.
> If I/O hangs for a long time, network read/write may timeout first and the
> peer may close the connection. Although the error was caused by a faulty
> local disk, disk check is not being carried out in this case.
