Darn, I was looking at the defaults for 0.8.2, which is why I thought it
was enabled. Thanks for the help. Works fine now that I enabled it.

Automatic preferred leader election hasn¹t been turned on in 0.8.1.1. It¹s
been turned on in latest trunk though.
The config name is ³auto.leader.rebalance.enable.

Does anyone have any insight into this? Am I correct that 0.8.1.1 should
be
running the leader election automatically? If this is a known issue, is
there any reason not to have a cron script that runs the leader election
regularly?
Thanks

I'm running 2.10-0.8.1.1, and rebalance will not trigger on it's own.

I think the leader imbalance means: For a single broker, add up all the
partitions it is leading (Y), and count the ones for which it's not the
preferred broker (X). The ratio of X:Y is the one being used.
I have about 10 topics spread between the 3 brokers, each with 4 or 8
partitions. If I restart broker A, wait 5 min, then restart B,
leadership
ends up entirely on C (even though A was in ISR when B went down).
Nothing
triggers on it's own. Triggering it manually works (with
bin/kafka-preferred-replica-election.sh).
Is there something I should be checking, or is there a downside to just
adding a cron job to trigger replica election once an hour?
Thanks
Steve
