I have seen an issue similar to this but with the /controller node. I am going to update https://issues.apache.org/jira/browse/KAFKA-1387 with the steps to reproduce the issue I ran into right now.
I don't know what steps caused what you ran into it is very odd that shouldn't happen. Were you doing anything with the cluster before this happened? starting/stopping nodes? any steps that might help reproduce it? any more info in any logs? I would recommend shutting down that node, make sure the znode is gone and starting it back up again. I also agree INFO is not a good status in that function, it is in a while(true) loop that may never end should at least be a WARN. /******************************************* Joe Stein Founder, Principal Consultant Big Data Open Source Security LLC http://www.stealth.ly Twitter: @allthingshadoop <http://www.twitter.com/allthingshadoop> ********************************************/ On Mon, Aug 4, 2014 at 10:23 PM, Bongyeon Kim <bongyeon....@gmail.com> wrote: > Hi, everyone. > > I'm using 0.8.1.1, and I have 8 brokers and 3 topics each have 16 > partitions and 3 replicas. > > I got unseen logs like below. this is occur every 5 seconds. > > > [2014-08-05 11:11:32,478] INFO conflict in /brokers/ids/2 data: > > {"jmx_port":9992,"timestamp":"1407204339990","host":"172.25.63.9","version":1,"port":9092} > stored data: > > {"jmx_port":9992,"timestamp":"1407204133312","host":"172.25.63.9","version":1,"port":9092} > (kafka.utils.ZkUtils$) > [2014-08-05 11:11:32,479] INFO I wrote this conflicted ephemeral node > > [{"jmx_port":9992,"timestamp":"1407204339990","host":"172.25.63.9","version":1,"port":9092}] > at /brokers/ids/2 a while back in a different session, hence I will backoff > for this node to be deleted by Zookeeper and retry (kafka.utils.ZkUtils$) > > > I hope to know the what makes this messages. > Is it OK that's not ERROR?
