Hi Liam,
> Any issues with partitions broker 2 is leader of? > Earlier today, broker 2 was not leader of any partitions. At that time, 2 appeared to be in ISRs of all partitions where 1 was leader, but 2 was not in any ISRs of partitions where 0 was leader. Currently, broker 2 is leader of 55 partitions, but does not appear to be in ISRs of any other partitions, whether 0 or 1 is leader. > Also, have you checked b2's server.log? > We don't see any logs that obviously indicate the problem, although we're also not sure what things we should be looking for. There are a few Zookeeper client timeouts, but haven't correlated that with anything yet. Thanks, Zach
