(Updated 2010-11-29 11:40:53.572161)
Review request for hadoop-mapreduce.
Changes
-------
- Reverted whitespace change
- Removed debugging helper method
Summary
-------
This change adds a new implementation of the raid block fixer that uses map
reduce jobs to fix missing/corrupt blocks, which allows us to fix a large
number of blocks quickly. The user can specify via a configuration variable
whether the old (local) or the new implementation should be used.
This addresses bug MAPREDUCE-2155.
