dhruba borthakur updated MAPREDUCE-1510: ---------------------------------------- Resolution: Fixed Hadoop Flags: [Reviewed] Status: Resolved (was: Patch Available) I just committed this. Thanks Rodrigo! > 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 > Attachments: MAPREDUCE-1510.1.patch, MAPREDUCE-1510.2.patch, > MAPREDUCE-1510.patch > > > 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
