Subject Recover datablocks
Date Fri, 13 Jul 2012 14:11:38 GMT
Hello all,

After a disk problem in one of our cluster's datanodes, there were some
corrupted files in the local file system. In the begining we did a
hadoop fsck -move that moved corrupted files to /lost+found. We have now
recovered the corrupted files in the local filesystem(datanode's
directory). Is there a way to recover the files from lost+found folder?

hadoop version: 0.20.2-cdh3u3
There exists no checkpoint of the namenode before moving the files to
/lost+found

Thanks,
Nikos
