Description

Currently, in DataNode.java, we have:

      LOG.info("Can't replicate block " + block
          + " because on-disk length " + onDiskLength 
          + " is shorter than NameNode recorded length " + block.getNumBytes());

This log is better off as a WARN as it indicates (and also reports) a corruption.
