Jun Rao commented on KAFKA-1019:
--------------------------------
I am not sure how reliable ZK 3.4.6 is. If you check the ZK admin page, it
shows you the command of listing all watchers registered. You want to check if
there is a child watcher on /brokers/topics.
Another thing is to avoid ZK session expiration, since it may expose some
corner case bugs.
> kafka-preferred-replica-election.sh will fail without clear error message if
> /brokers/topics/[topic]/partitions does not exist
