DN should log a WARN, not an INFO when it detects a corruption during block transfer
------------------------------------------------------------------------------------

                 Key: HDFS-2349
                 URL: https://issues.apache.org/jira/browse/HDFS-2349
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: data-node
    Affects Versions: 0.20.204.0
            Reporter: Harsh J
            Assignee: Harsh J
            Priority: Trivial
             Fix For: 0.24.0


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.
