[jira] [Commented] (ZOOKEEPER-2712) MiniKdc test case intermittently failing due to principal not found in Kerberos database

[Rakesh R (JIRA)]

 ] 

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.

Re: Contributing to Zookeeper

[Jordan Zimmerman]

Atri,

Docs regarding ZooKeeper are abundant on the Internet. Like all Apache 
projects, the best place to start is the project website: 
http://zookeeper.apache.org . Also, like most 
Apache projects there is a wiki with tons of information: 
https://cwiki.apache.org/confluence/display/ZOOKEEPER/Index
