----------------------------------------
Resolution: Won't Fix
Better to fix MAPREDUCE-2185
> DistributedRaidFileSystem should implement getFileBlockLocations()

> Key: MAPREDUCE-2186
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-2186
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: contrib/raid
> Reporter: Ramkumar Vadali
> Assignee: Ramkumar Vadali
>
> If a RAIDed file has missing blocks,
> DistributedRaidFileSystem.getFileBlockLocations() would return no block
> locations. This could lead a client to believe that the file is not readable.
> But if parity data is available, the file actually is readable.
> It would be better to implement getFileBlockLocations() and return the
> location of the parity blocks that would be needed to reconstruct the missing
> block.
