Subject [jira] [Commented] (HDFS-10245) Fix the findbug warnings in branch-2.7
Date Tue, 05 Apr 2016 02:34:25 GMT

    [ https://issues.apache.org/jira/browse/HDFS-10245?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15225546#comment-15225546
] 

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.
