RAID should regenerate parity files if they get deleted
-------------------------------------------------------
Key: MAPREDUCE-1510
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1510
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: contrib/raid
Reporter: Rodrigo Schmidt
Assignee: Rodrigo Schmidt
Currently, if a source file has a replication factor lower or equal to that
expected by RAID, the file is skipped and no parity file is generated. I don't
think this is a good behavior since parity files can get wrongly deleted,
leaving the source file with a low replication factor. In that case, raid
should be able to recreate the parity file.
