Subject [jira] Created: (MAPREDUCE-1908) DistributedRaidFileSystem does not handle ChecksumException correctly

DistributedRaidFileSystem does not handle ChecksumException correctly
---------------------------------------------------------------------

                 Key: MAPREDUCE-1908
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1908
             Project: Hadoop Map/Reduce
          Issue Type: Bug
            Reporter: Ramkumar Vadali


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.
