__consumer_offsets rebalance

[Anderson Goulart]

Hi,

I am running kafka 0.8.2.1 under aws instances with multiple 
availability zones. As we want a rack aware partition replication, we 
have our own partition layout distribution, to make sure all partitions 
are well balanced between nodes, leaders and availability zones.

The problem arises with __consumer_offsets internal topic. In our 
current environment it has 50 partitions and are all under the same AZ, 
with an unbalanced leader (all wrong!)

The question is: should I manually change its partition layout 
distribution as I do for the other topics? Is it safe to reassign the 
new layout for this internal topic, using kafka-reassign-partitions.sh?


Thanks, Anderson
