[jira] Created: (MAPREDUCE-1704) Parity files that are outdated or nonexistent should be immediately disregarded

Parity files that are outdated or nonexistent should be immediately disregarded
-------------------------------------------------------------------------------

                 Key: MAPREDUCE-1704
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1704
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: contrib/raid
    Affects Versions: 0.22.0
            Reporter: Rodrigo Schmidt
            Assignee: Rodrigo Schmidt
             Fix For: 0.22.0


In the current implementation, old or nonexistent parity files are not immediately disregarded. Absence will trigger exceptions, but old files could lead to bad recoveries and maybe data corruption. This should be fixed.
