>                 Key: MAPREDUCE-2036
>                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2036
>             Project: Hadoop Map/Reduce
>          Issue Type: Improvement
>          Components: contrib/raid, harchive
>            Reporter: Wittawat Tantisiriroj
>            Assignee: Wittawat Tantisiriroj
>            Priority: Minor
>         Attachments: hdfs-raid.tar.gz, MAPREDUCE-2036.patch, RaidTool.pdf

> Features:
> 1) HAR-like Tool
> 2) RAID5/RAID6 & pluggable interface to implement additional coding
> 3) Enable to group blocks across files
> 4) Portable across cluster since all necessary metadata is embedded
> While it was developed separately from HAR or RAID due to time constraints, it would
make sense to integrate with either of them.
