partition count multiples - adverse effects on rebalancing?

Just curious - how is rebalancing handled when the number of potential
consumer threads isn't a multiple of the number of partitions?

IE If I have 9 partitions and 6 threads - will the cluster be forever
trying to balance this?

If you have less threads than partitions, some thread will process
multiple partitions.
