PerformanceEvaluation generates 10x the number of expected mappers
------------------------------------------------------------------

                 Key: HBASE-5401
                 URL: https://issues.apache.org/jira/browse/HBASE-5401
             Project: HBase
          Issue Type: Bug
          Components: performance
            Reporter: Oliver Meyn


With a command line like 'hbase org.apache.hadoop.hbase.PerformanceEvaluation randomWrite
10' there are 100 mappers spawned, rather than the expected 10.  The culprit appears to be
the outer loop in writeInputFile which sets up 10 splits for every "asked-for client".  I
think the fix is just to remove that outer loop.
