Subject [jira] [Commented] (ZOOKEEPER-2712) MiniKdc test case intermittently failing due to principal not found in Kerberos database
Date Tue, 21 Mar 2017 01:12:41 GMT

    [ https://issues.apache.org/jira/browse/ZOOKEEPER-2712?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15933929#comment-15933929

Michael Han commented on ZOOKEEPER-2712:
----------------------------------------

Thanks Rakesh for the explain on the root cause of the issue. I give +1 on the patch.

Regarding find bugs, I tend to agree that they are not blockers but I'd like to make sure
that these warnings are not introduced after 3.4.9 - in other words, Do these warnings, or
a large subset of it also exists in 3.4.9 (and possibly previous 3.4.x releases)? If that
is the case I think we can postpone fixing these, as it is not regression and previous releases
all contain them. [~rakeshr] Can you please confirm that previous 3.4.x release (at leaset
3.4.9) has similar scale of find bug warnings?
