      Description

      Fix disk checker issues reported by Kihwal Lee in HADOOP-13738:

      When space is low, the os returns ENOSPC. Instead simply stop writing, the drive is marked bad and replication happens. This make cluster-wide space problem worse. If the number of "failed" drives exceeds the DFIP limit, the datanode shuts down.
