Brahma Reddy Battula commented on HDFS-10245:
---------------------------------------------
bq. There was 1 findbugs found in prepatch.
Yes exactly, this Jira itself is to fix that. In which case, findbug report
should point to post-patch findbugs. No matter whether its empty.
No explicit filtered report for findbugs induced from the patch is not required.
But, {{0 new + 0 unchanged - 1 fixed = 0 total (was 1)}} this message at the
end, similar to checkstyle fixes will help to indentify changes.
> Fix the findbug warnings in branch-2.7
