      Description

      (Recreating HDFS-1171 since RAID is in mapreduce)

      RaidNode currently does not fix missing blocks. The missing blocks have to be fixed using RaidShell.
      This task proposes that recovery be more automated:
      1. RaidNode periodically fetches a list of corrupt files from the NameNode
      2. If the corrupt files can be fixed using RAID, it should generate the block.
      3. Choose a datanode and send the block contents along with checksum to the datanode.
