Ian Varley commented on HBASE-5401: ----------------------------------- Hey Oliver, I see in your blog post (http://gbif.blogspot.com/2012/02/performance-evaluation-of-hbase.html) that you patched this issue. Mind posting that patch back here? > 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: test > 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. -- This message is automatically generated by JIRA.
