> We have a very typical use-case of wanting to retrieve all columns under a single row,
single family.
> Benchmarking regularly reproduces the same result.  Using HTable.getScanner().next()
to get the RowResult works twice as fast as HTable.getRow().
> This is related to HBASE-631 by jdcryans which added this functionality to getRow().
