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.
