I setup a 2 node cluster. With replication-factor 2. Create 10 topics with 131
partitions each then tried to do a controlled shutdown of broker #2 (which is
the current elected leader).
(Sorry, our Broker #1 and Broker #2 server times are 6h off, I will have to get
that fixed).
According to Zookeeper Broker #2 is still the controller:
[zk: tm1mwwm001:2181(CONNECTED) 13] get /controller

What's the controller value in the zk path (see
https://cwiki.apache.org/confluence/display/KAFKA/Kafka+data+structures+in+Zookeeper)?
Any error in the controller/state-change log?
