Akira AJISAKA commented on HDFS-10485:
--------------------------------------

Thanks [~xiaobingo] for the review comment.
bq. Can you explain why this has been removed?
My bad, fixed in 03 patch.
bq. And also, this issue has no cause and effect relation to HDFS-10341, am I right?
Yes, you are right. In this jira, precommit jenkins job ran on branch-2 and found that branch-2
is already broken.
