             Summary: Add a new option in PE to indicate the current number of rows in the test table
                 Key: HBASE-25655
                 URL: https://issues.apache.org/jira/browse/HBASE-25655
             Project: HBase
          Issue Type: Improvement
          Components: PE
            Reporter: Baiqiang Zhao
            Assignee: Baiqiang Zhao


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.
