DistributedRaidFileSystem should unraid only the corrupt block
--------------------------------------------------------------
Key: MAPREDUCE-2248
URL: https://issues.apache.org/jira/browse/MAPREDUCE-2248
Project: Hadoop Map/Reduce
Issue Type: Improvement
Reporter: Ramkumar Vadali
Assignee: Ramkumar Vadali
DistributedRaidFileSystem unraids the entire file if it hits a corrupt block.
It is better to unraid just the corrupt block and use the rest of the file as
normal. This becomes really important when we have tera-byte sized files.
