Thanks [~anoop.hbase]. Yes, use --size can not hot spot one or few regions for 
randomRead and randomSeekScan. My example may be a bit special. But what about 
asyncRandomRead, scanRangeXX etc.

> When we have written 100000 rows in TestTable with 10 preSplits. Then we want 
> to test randomRead with 10 threads, per thread read 1000 rows. But the range 
> of all read keys is in [0, 10000], all in the first region. It may cause 
> hotspot problem, and the result is not accurate.
> This issue add a new option "initRows" to  solve this problem.
