To determine this, we will specifically be observing a Compactor process during out tests, but the findings should apply to any Accumulo Server process. + +### Test Scenario +There could be a scenario where the amount of memory on a machine limits the number of compactors that can be run. For example, on a machine with 32G of memory, if each compactor process uses 6G of memory, we can only "fit" 5 compactors on that machine (32/6=5.333). Since each compactor process only runs on a single core, we would only be utilizing 5 cores on that machine where we would like to be using as many as we can.
