> Fix disk checker issues reported by [~kihwal] 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.
