Appy commented on HBASE-15841:
------------------------------
Good we already have fatal exception.
bq. opts.size will be the default in that last case
Shouldn't correct value of opts.size in last case be "1.0f*num clients" GB.
The reason why i asked for updating the size is, if in future, new logic is
added downstream which depends on size, it'll get incorrect size when --rows is
specified. If the person making the change is lucky, he/she might figure out
the bug sooner, in worst case, the bug will lie around until someone spends a
bit of time going back and debugging it.
Bottom line, have a set of mutually inconsistent values in TestOptions can lead
to bug in future.

> Carried my comment on HBASE-15403 to here:
> Recently when I ran PerformanceEvaluation, I did notice some problem with the
> number of rows.
> hbase org.apache.hadoop.hbase.PerformanceEvaluation --table=TestTable1
> randomWrite 1
> hbase org.apache.hadoop.hbase.PerformanceEvaluation --table=TestTable5
> randomWrite 5
> hbase org.apache.hadoop.hbase.PerformanceEvaluation --table=TestTable10
> randomWrite 10
> hbase org.apache.hadoop.hbase.PerformanceEvaluation --table=TestTable10
> randomWrite 20
> All produced similar number of rows, and on the file system, they look like
> in similar size as well:
> hadoop fs -du -h /apps/hbase/data/data/default
> 786.5 M /apps/hbase/data/data/default/TestTable1
> 786.0 M /apps/hbase/data/data/default/TestTable10
> 782.0 M /apps/hbase/data/data/default/TestTable20
> 713.4 M /apps/hbase/data/data/default/TestTable5
> HBase is 1.2.0. Looks like a regression somewhere.
