> Need a command line option in RaidShell to fix blocks using raid

> Key: HDFS-1453
> URL: https://issues.apache.org/jira/browse/HDFS-1453
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: contrib/raid
> Reporter: Ramkumar Vadali
>
> RaidShell currently has an option to recover a file and return the path to
> the recovered file. The administrator can then rename the recovered file to
> the damaged file.
> The problem with this is that the file metadata is altered, specifically the
> modification time. Instead we need a way to just repair the damaged blocks
> and send the fixed blocks to a data node.
> Once this is done, we can put automation around it.
