Funny, but this is part of a talk that I submitted to Strata.... 64GB and HBase isn't necessarily a 'large machine'.
If you're running w 12 cores, you're talking about a minimum of 48GB just for M/R. (4GB a core is a good rule of thumb ) Depending on what you want to do, you could set aside 8GB of heap and tune that, but even that might not be enough...
