      Description

      ChecksumException reports the offset of corruption within a block,
      whereas DistributedRaidFileSystem.setAlternateLocations was expecting it
      to report the offset of corruption within the file.

      The best way of dealing with a missing block/corrupt block is to just
      use the current seek offset in the file as the position of corruption.
