RaidNode should optionally dispatch map reduce jobs to fix corrupt blocks (instead of fixing locally) -----------------------------------------------------------------------------------------------------
Key: MAPREDUCE-2155 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2155 Project: Hadoop Map/Reduce Issue Type: Improvement Reporter: Patrick Kling Recomputing blocks based on parity information is expensive. Rather than doing this locally at the RaidNode, we should run map reduce jobs. This will allow us to quickly fix a large number of corrupt or missing blocks. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
