-------------------------

Release Note: Changes how many tasks PE runs when clients are mapreduce.
Now tasks == client count. Previous we hardcoded ten tasks per client instance.
Status: Resolved (was: Patch Available)
Pushed. Makes sense. This baffled you and Oliver. Thats enough. Thanks for the
patch [~easyliangjob]

> 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.
