Baiqiang Zhao commented on HBASE-25655:
---------------------------------------
After adding the initRows option, rows and size can be completely mutually
exclusive.
Only one of rows and size can be selected to control the perClientRunRows.
> Add a new option in PE to indicate the current number of rows in the test
> table

> 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.
