Abdel, I didn't ask about having more than one drillbit per node. I asked about the number of drillbits per cluster. For instance, if I had a 1000 node Hadoop cluster, should I install drillbits on each node? Or, is there some point at which the interaction of 1000 drillbits causes contention resulting in a plateau or decline of performance?
