Subject Automatic recover corrupted files
Date Thu, 25 Nov 2010 02:35:22 GMT
We have a corrupted file which has only one block.
It turns out that all checksum files of the replicas
are corrupted... but the data files are OK...

How to recover this file?

I can think of trying to use shell get file with -ingorecrc
option. Then put it into HDFS again...
But can the system automatically recover
this until it is too late?

Thanks
