Subject [jira] [Commented] (ZOOKEEPER-2712) MiniKdc test case intermittently failing due to principal not found in Kerberos database
Date Sun, 19 Mar 2017 17:47:41 GMT

    [ https://issues.apache.org/jira/browse/ZOOKEEPER-2712?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15931855#comment-15931855

Rakesh R commented on ZOOKEEPER-2712:
-------------------------------------

bq. Regarding find bug warnings - I tried find bugs (3.0.1) locally and I also get 97 warnings.
I suspect we did not get such warnings either because we did not run find bugs at all for
branch-3.4, or find bug version updates. I think we should fix the warnings before releasing
of 3.4.10, not sure if you agree with this or not. Regardless of this, I think fixing findbug
warning is out scope of this particular JIRA and we could use another JIRA to track it (same
for the javadoc warnings).

Thank you [~hanm] for bringing the findbug warnings point. Its true, Jenkins was not running
findbug tool for branch-3.4 and the report was not visible. I personally would like to avoid
postponing the 3.4.10 release even further as there are many critical, security defects fixed
and quorum auth sasl feature available in this. IMHO, we should fix findbugs if anything critical
and should cut a {{3.4.10}} release and all the other warnings can be pushed to {{3.4.11}}?
I have quickly gone through the warnings and didn't notice any critical items. Please feel
free to add if you would like to discuss any specific case. Probably, could raise a jira to
fix those and continue discussion over there.
