----------------------------------------------------------------
Key: HBASE-5527
URL: https://issues.apache.org/jira/browse/HBASE-5527
Project: HBase
Issue Type: Improvement
Components: performance
Affects Versions: 0.92.0
Reporter: Benoit Sigoure
Assignee: Benoit Sigoure
Priority: Minor
Attachments: 0001-PerformanceEvaluation-fixes.patch
When running {{PerformanceEvaluation}} with {{--nomapred}} it's hard to locate
all the lines saying {{Finished 14 in 292979ms writing 2000000 rows}} in the
output. This change adds a couples line to summarize the run at the end, which
makes parsing and scripting the output easier:
{code}
12/03/06 00:43:58 INFO hbase.PerformanceEvaluation: [RandomWriteTest] Summary
of timings (ms): [15940, 15776, 15866, 15973, 15682, 15740, 15764, 15830,
15768, 15968, 15921, 15755, 15963, 15818, 15903, 15662]
12/03/06 00:43:58 INFO hbase.PerformanceEvaluation: [RandomWriteTest] Min:
15662ms Max: 15973ms Avg: 15833ms
{code}
Patch also removes a couple minor code smells.
