tianhang tang updated HBASE-27873:
----------------------------------
    Description: 
When we use Asyncfs for WAL, could see many WARN logs like this:

!image-2023-05-18-15-51-33-823.png!

namenode#complete is a relatively heavy operation, and sometimes it takes 
seconds.

So we can reduce this log, just as what

 do.
