This modification makes `barrier()` always returns true, and makes `NNbench_reports.log`'s "maps that missed the barrier" metric always be zero. In a large test configuration with thousands of mappers, Yarn takes more than 2 minutes(the default barrier time) to start up all the mappers. The `barrier()` function is important to make the results meaningful. @aajisaka I think we should revisit this commit. -- This is an automated message from the Apache Git Service.
