Date Mon, 16 May 2016 21:50:12 GMT
Jerry He created HBASE-15841:
--------------------------------

             Summary: Performance Evaluation tool total rows may not be set correctly
                 Key: HBASE-15841
                 URL: https://issues.apache.org/jira/browse/HBASE-15841
             Project: HBase
          Issue Type: Bug
            Reporter: Jerry He
            Priority: Minor


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.
