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.
