Thanks for the reply. I checked the default max heap size for java on the nodes and it turns out its 16G. So now I have to start zookeeper with a reasonable value for heapsize. What are the factors that would impact the heap size of zookeeper? Is it more tables in hbase or is is the number of regions?
