recommendations for size of zookeeper instances

since druid zookeeper nodes have barely any cpu/ mem activity is it ok to run them on t2.small or t2.medium instances?
I am curious what size boxes you guys use for your zk deployments

Hi Prashant, 3 m1.xlarges are a reasonable choice for zookeeper nodes. 8g heaps with 256m new size seems reasonable for these nodes.
