If I have to.... how me reducers I should have?? as many as number of regions?? I have read about HRegionPartitioner, but it has some limitations, and you have to be sure that any region isn't going to split while you're putting new data in your table. Is it only for performance? what could it happen if you put too many data in your table and it splits an region with a HRegionPartitioner?
