Perhaps you saw this in http://www.slideshare.net/schubertzhang/hbase-0200-performance-evaluation? ZooKeeper is managed external of HBase in production. It should not really require a ~4G heap space. RegionServer should need all the extra RAM it can get, if am right, so set it for those surely (more than 4 is good too, if available). -- Harsh J http://harshj.com
