   Thanks @cxzl25 for your patch. I have a question about it and looking forward your feedback.
   Can this change improve the namenode performance? I see that some places specially remove this judgment, and use log.info("{}", XXX) replace it.
   
   Or can you do some performance test for it? use this judgment or not.
