> Currently, in DataNode.java, we have:
> {code}
>       LOG.info("Can't replicate block " + block
>           + " because on-disk length " + onDiskLength 
>           + " is shorter than NameNode recorded length " + block.getNumBytes());
> {code}
> This log is better off as a WARN as it indicates (and also reports) a corruption.
