Matt Warhaftig commented on HBASE-13708:
----------------------------------------
The rowRangeSize is in the logging at the start with:
{noformat}
2015-08-14 07:24:25,523 INFO [main] hbase.PerformanceEvaluation:
RandomReadTest test run options={..."rowRangeSize":100...
{noformat}
And then at PE completion:
{noformat}
2015-08-14 07:24:27,148 INFO [TestClient-0] hbase.PerformanceEvaluation:
Finished class org.apache.hadoop.hbase.PerformanceEvaluation$RandomReadTest in
92ms at offset 0 for 10 rows from a range of 100 rows (0.11 MB/s)
{noformat}
The line you highlighted
{noformat}
2015-08-14 07:24:27,013 INFO [TestClient-0] hbase.PerformanceEvaluation:
Sampling 1 every 1 out of 10 total rows.
{noformat}
is logging for sample sizing versus number of reads so 10 total rows is apt to
display.
If you want rowRangeSize to be more prominent in the logging I can append it to
that line.

> When specifying --rows=YYY for randomReads in PE, it will read YYY rows but
> only betweem 0 and YYY.
> We might want to read YYY rows randomly between 0 and ZZZ.
> YYY should only be the number of rows we want to ready. Not the high range.
