Updated patch for branch-1 and patch for trunk.

On trunk, doing similar change to the following line of code, would make it consistent with branch-1.

      LOG.info("Image file of size " + curFile.length() + " loaded in " 
          + (now() - startTime)/1000 + " seconds.");

Also if this is only applicable to branch-1, then please change Affects Version/s field accordingly.

BTW do we print the complete path to the editlog file that is loaded by namenode?

+1 for the patch.

edits file location is already logged on branch-1, start logging image file location.
