The above batch update description implies batch update of columns
Hi,
I'm noticing that since the HClient/HRegionServer interface only allows
for a per-column put(), there is a lot of RPC and some lease management
overhead when writing large amounts of data. For example:

Text rowKey = new Text(i+"");
