      Description

      Currently in various places (metrics, dfsadmin -report, fsck, logs) we use the term "corrupt" to refer to blocks which have an out-of-date generation stamp. Since out-of-date blocks are a fairly normal occurrence if a DN restarts while data is being written, we should be avoid using 'scary' works like corrupt. This may need both some textual changes as well as some internal changes to count the corruption types distinctly.
