[jira] [Created] (HBASE-20517) Fix PerformanceEvaluation 'column' parameter

Andrew Purtell created HBASE-20517:
--------------------------------------

             Summary: Fix PerformanceEvaluation 'column' parameter
                 Key: HBASE-20517
                 URL: https://issues.apache.org/jira/browse/HBASE-20517
             Project: HBase
          Issue Type: Bug
          Components: test
            Reporter: Andrew Purtell
            Assignee: Andrew Purtell
             Fix For: 3.0.0, 2.1.0, 1.5.0, 1.2.7, 1.3.3, 2.0.1, 1.4.5


PerformanceEvaluation's 'column' parameter looks broken to me. 

To test:
1. Write some data with 20 columns.
2. Do a scan test selecting one column.
3. Do a scan test selecting ten columns.

You'd expect the amount of data returned to vary but no, because the read side isn't selecting the same qualifiers that are written. Bytes returned in case 3 should be 10x those in case 2.

I'm in branch-1 code at the moment. Probably affects trunk too.
