qiang Liu commented on HDFS-14303:
----------------------------------

[~hexiaoqiao] I do some change and submit a new patch 
[^HDFS-14303-branch-2.9.013.patch]

a. remove logger check logics

b. looks like [~hadoopqa] got some thing wrong, the branch-2.9 compile failed 
even before patch, and I run dev-support/bin/test-patch locally, all pass and 
no checkstyle problem.

c. becase the only thing affected is a warn log, so there is no easy way to 
check another way

thanks and looking forward your response.
